Incremental work, starting to take shape
Ah, much cleaner
Added change pw buttons; encryption is very nearly done.
@apprb there is one question and one TODO that you should look over in privacyform.cpp, as well as a TODO in historykeeper.cpp
Also both the encryption settings box and the pw dialog lineedits should probably be in a QGridLayout... but I don't really want to do that by hand :P
