Added the custom and test scripts to the buildbot (#2658)

* Added the custom and test scripts to the buildbot

All scripts inside the custom and test npc directory are now parsed and executed automatically by the buildbot.
The only exceptions are the custom battleground scripts that would cause duplication warnings.

Thanks to @Jeybla for the Unix script!
