Subject: Break out preference type names, type descriptions, string
 representations, and default status out of write_prefs and into their own
 routines. Split the corresponding custom preference write callbacks. Fix an
 apparent memory leak in the hidden column callback.

Add an initial preferences dialog to the Qt port. Use the new preference
routines to implement an "Adavanced" page similar to the "about:config"
page available in many web browsers. Standard pages will hopefully follow
soon.

Remove some QDebug includes and make sure our QTreeWidgets have uniform
row heights set.
