* Server: delegate mod management & config to ServerModConfiguration (rename it to ServerModManager)
* Use c++11 range based loops
* Add unittests + experimental/default mod as a test case to permit testing mod loading in future tests
* isFreeServerActiveObjectId is now part of ServerEnvironment
* getFreeServerActiveObjectId is now part of ServerEnvironment
* StaticObject constructor now take ServerActiveObject instead of type + string. This permits to remove a big string copy in some code parts
* ObjectRef::set_local_animation: fix wrong lua return (should push a boolean, currently returns nil)
* ObjectRef::set_eye_offset: fix wrong lua return (should push a boolean, currently returns nil)
* Fix various Server functions which depends on RemotePlayer objet and return true/false when player object is nil whereas it's a caller implementation error. Change those bool functions to void and add sanitize_check call instead. Current callers are always checking player object validity
* Optimize Server::setClouds : use CloudParams object ref instead of attribute deserialization from structure & perform RemotePlayer::setCloudParams directly in server class like many other calls
* Optimize Server::SendCloudParams: use CloudParams object ref instead of deserialized attributes
Use the --color command line parameter instead of a setting for coloured logs
This fixes the missing warningstream bug, g_settings->get mustn't be used there.
Also, the decision about en- or disabling log colours fits better to the command line parameters than minetest settings.
Change to --worldlist instead of --world list.
Gets rid of --worldpath parameter added as part of this pull request,
instead moving the listing function to a command --worldlist that
accepts either name, path, or both and prints out the corresponding
information.
Returns the decoration ID for the provided decoration name string.
For use with gennotify, to know the decoration IDs for use in
'minetest.set_gen_notify'.
