v0.1.11 Add remote querying

You can now have a filesurf daemon running in the background on one machine and perform searches from a different machine.
To start the daemon:

filesurf --daemon --host='<ip>:<port>'

ip can be left blank like below:

filesurf -daemon --host=':9999'

To use a remote daemon:

filesurf --host='<ip>:<port>'

Everything is remains the same, with all the queries that could be done before.
