freqit.ini needs a different method of specifying directories

According to freqit.ini, a comma separated list of directories must be provided on the Dir line. The docs for .ini files state that the maximum length of a key value is 1023 characters, however I have 1820 directories so there's no way for me to even come close to adding them all.

There needs to be a different method of specifying the groups you wish to expose to freqit.
