Clean up preference saving code
The old code (on purpose) didn't try to differentiate "nonexisting boolean configuration" with "existing boolean configuration set to false", which is problematic if we optimize the saving to not save default preferences at all. Which this does. So in addition to the logic to know about default preferences, this has to change the interfaces for the PREF_BOOL reading code so that you can tell the difference between "no value" and "false". And since the previous calling convention was an abomination of doing pointer casting and having case-statements for the config types, change that while at it. Both from a usage perspective *and* from a back-end perspective it is actually much simpler to just have different functions for the string vs boolean config read/write versions. The OSX versions in particular end up being one-liners. (The GConf library is a nightmare, and doesn't seem to have any way to know whether a boolean value exists or not, so you have to read it as a GConfVal and then turn it into a gboolean rather than just get the "oh, it didn't exist" as an error value).
