After moving StatusDat to monitoring/Backends and changing the
inheritance to Library/Icinga/Data, a few changes must be reflected in the tests:
- Move tests to monitoring module
- Change $this->backend references in StatusDat Queries to $this->ds
- Added LibraryLoader to ease requiring of libaries (to be discussed)

The function tokens in the Expression handler didn't
work after they were rewritten, as the rewrite was
missing in certain files. This is fixed now
