Enhance filters in SeriesTreeWidget a little more

Allow operators in filter. Operators are only valid if it's a
NumericQuery. Operators are <>=. Also allow postfixes for numbers: k, m,
g for kilobytes, megabytes and gigabytes.

Also fix a little usability bug when filtering. If the result set was
empty, the root item was collapsed. On the next search with a result,
the root item was still collapsed. Since it wasn't shown there was no
way to expand it.
