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
