*	Mainmenu: Refactor tab UI code	Rui914	2016-04-08
| | | | | |	- Use local variables for tabs in place of globals - Merge together if statements where possible - Replace manual table searching code with indexof where possible
*	builtin: Fix `print` crashing on nil "holes".	Diego Martinez	2016-02-08
| | | | | | | | | | | | |	The engine implementation of `print` packs the varargs into a table and passes the table directly to `table.concat`. If you pass any value not supported by `table.concat` (particularly `nil`), the server crashes. This is unexpected behavior, as `print` is supposed to be able to work with anything. This patch changes the implementation so it first converts all arguments using `tostring`, which fixes the issue and makes the custom `print` function compatible with the stock Lua behavior.
*	Add server side ncurses terminal	est31	2015-11-06
| | | | | | | | | | | | | | | | | | | | | | | |	This adds a chat console the server owner can use for administration or to talk with players. It runs in its own thread, which makes the user interface immune to the server's lag, behaving just like a client, except timeout. As it uses the same console code as the f10 console, things like nick completion or a scroll buffer basically come for free. The terminal itself is written in a general way so that adding a client version later on is just about implementing an interface. Fatal errors are printed after the console exists and the ncurses terminal buffer gets cleaned up with endwin(), so that the error still remains visible. The server owner can chose their username their entered text will have in chat and where players can send PMs to. Once the username is secured with a password to prevent anybody to take over the server, the owner can execute admin tasks over the console. This change includes a contribution by @kahrl who has improved ncurses library detection.
*	Refactor logging	ShadowNinja	2015-10-14
| | | | | | | | |	- Add warning log level - Change debug_log_level setting to enumeration string - Map Irrlicht log events to MT log events - Encapsulate log_* functions and global variables into a class, Logger - Unify dstream with standard logging mechanism - Unify core.debug() with standard core.log() script API
*	Add strict module	ShadowNinja	2014-11-19
| | | |	Also fix leaking globals found by it.
*	Fix regression main_menu_script setting not working any longer	sapier	2014-06-14
|
*	Use "core" namespace internally	ShadowNinja	2014-05-08
|
*	Organize builtin into subdirectories	ShadowNinja	2014-05-07
