fix
QFuse no longer runs its own QThread
fixed a multithread induced QLocalSocket error by _not_ moving QFuse into a seperate QThread
after ctrl+c this error occures
     QSocketNotifier: Invalid socket 13 and type 'Read', disabling...
     QObject::connect: Cannot queue arguments of type 'QAbstractSocket::SocketState'
     (Make sure 'QAbstractSocket::SocketState' is registered using qRegisterMetaType().)

see this for more details:

still got this strange bug in QFuse.cpp::readSocket(). no clue how to fix that...
