Basic support for configuring which mods to load for each world settings.h: added function to return all keys used in settings, and a function to remove a setting mods.{h,cpp}: added class ModConfiguration that represents a subset of the installed mods. server.{h,cpp}: server does not load add-on mods that are disabled in the world.mt file. mods are disabled by a setting of the form "load_mod_<modname> = false". if no load_mod_<modname> = ... setting is found, the mod is loaded anyways for backwards compatibilty. server also complains to errorstream about mods with unstatisfied dependencies and about mods that are not installed. guiConfigureWorld.{h,cpp}: shows a treeview of installed add-on mods and modpacks with little icons in front of their name indicating their status: a checkmark for enabled mods, a cross for disabled mods, a question mark for "new" mods Mods can be enabled/disabled by a checkbox. Mods also show a list of dependencies and reverse dependencies. double-click on a mod in dependency or reverse dependency listbox selects the corresponding mod. Enabling a mod also enables all its dependencies. Disabling a mod also disables all its reverse dependencies. For modpacks, show buttons to enable/disable all mods (recursively, including their dependencies) in it. Button "Save" saves the current settings to the world.mt file and returns to the main menu. Button "Cancel" returns to main menu without saving. basic keyboard controls (if the proper widget has keyboard focus): up/down: scroll through tree of mods left/right: collaps/expand a modpack space: enable/disable the selected mod

Rewrite client media download and support hash-based remote download Move most of the media-related code in client.cpp into a new class ClientMediaDownloader (clientmedia.cpp, clientmedia.h). Among other things, this class does the following things: - Download [remote_server][sha1] instead of [remote_server][name]. This is to support servers that provide the same file name with different contents. - Initially fetch [remote_server]index.mth. This file should follow the Minetest Hashset format (currently version 1) and contain a list of SHA1 hashes that exist on the server. - The list of needed SHA1s is uploaded (via HTTP POST) when index.mth is requested, so servers can optionally narrow down the list to the needs of the client. - If index.mth is missing (HTTP response code 404), we enter compat mode, fetching [remote_server][name] as before this commit. - remote_server can now contain multiple servers, separated by commas. The downloader code attempts to split requests between the different servers, as permitted by each server's index.mth. If one server claims to have a file but actually doesn't (or something fails), we ask a different server that also claims to have it. - As before, when none of the remote servers provide a particular file, we download it via the conventional method, i.e. using the minetest protocol: TOSERVER_REQUEST_MEDIA / TOCLIENT_MEDIA. - Bugfix: Every downloaded file's SHA1 is now verified against the SHA1 announced by the minetest server (before loading it and inserting it into the file cache). - Bugfix: Only send TOSERVER_RECEIVED_MEDIA when we actually have all media. This should fix #863.

This file should follow the Minetest Hashset format (currently version 1) and contain a list of SHA1 hashes that exist on the server. - The list of needed SHA1s is uploaded (via HTTP POST) when index.mth is requested, so servers can optionally narrow down the list to the needs of the client. - If index.mth is missing (HTTP response code 404), we enter compat mode, fetching [remote_server][name] as before this commit. - remote_server can now contain multiple servers, separated by commas. The downloader code attempts to split requests between the different servers, as permitted by each server's index.mth. If one server claims to have a file but actually doesn't (or something fails), we ask a different server that also claims to have it. - As before, when none of the remote servers provide a particular file, we download it via the conventional method, i.e. using the minetest protocol: TOSERVER_REQUEST_MEDIA / TOCLIENT_MEDIA. - Bugfix: Every downloaded file's SHA1 is now verified against the SHA1 announced by the minetest server (before loading it and inserting it into the file cache). - Bugfix: Only send TOSERVER_RECEIVED_MEDIA when we actually have all media. This should fix #863.

Rewrite client media download and support hash-based remote download Move most of the media-related code in client.cpp into a new class ClientMediaDownloader (clientmedia.cpp, clientmedia.h). Among other things, this class does the following things: - Download [remote_server][sha1] instead of [remote_server][name]. This is to support servers that provide the same file name with different contents. - Initially fetch [remote_server]index.mth.
