Qt: Add zoom and column resize actions.

Plumb signals and slots for changing the text size in the main window.
Remove the bold font code from WiresharkApplication. It was only used in
ByteViewText. Adjust the icons a bit.

Bug: When we change the font preferences the packet list stops drawing
cached strings. I haven't been able to track down the cause.
