Subject: Implemented extended filters

Extended the filter function in SeriesTreeWidget. By passing an operator
to the filter dialog series can be filtered. The code generates highly
dynamic SQL queries. I hope I didn't introduce possible SQL injections.

Filter operators:
g: genre
a: actor
q: quality
n: filename
d: dvd no
s: size
