At this time, only E2 is working.
Fixing a lot of old code (monster is no longer id 0).
package.paths configured from eressea.ini
install directory configured from eressea.ini
moving building_action into a seaprate module (it's deprecated)
new tests in progress.
remove giveitem.c attribute, the name clashed with a trigger,
and it was only part of an arena that is gone from the game, I think.
