multiply Library Folders feature from library_features branch, builds untested
fixed update code and removed useless stuff from initial patch
dlgprefplaylist uses library instance instead of sql connection
basic track adding works
directoryDAO query don't work with bindvalue
directory doa works with bindValue now

Because Fieldscaper add '' marks around a direcotry entry Qt can't work

everything work again I just need to replace ' with an empty string
remove checksums from schema.xml
