Added support for a preliminary Preferences Dialog

Dirk asked me to try to make it more modern, so I
used as a base, the Firefox preferences. currently
it saves / loads the preferences, and also smits
a signal 'preferencesChanged' that should be connected
to anything that uses preferenes, via the PreferencesDialog::intance()
object. In the future, I plan to make it have a signal / slot for each
member that changes.

I also moved the icons to a new folder this time, because the
amount of icons is now more than just two, and it was
becoming messy.
