Added some convenience wrappers to libmana.lua

Global functions 'warn', 'info', 'debug' as shortcuts to the respective
'log' call, which also support passing multiple parameters at the same
time, which will be separated by spaces.

Global tables 'map' and 'world' which provide convenient read/write
access to map and world state variables.
