Gtk3

[Robert Fewell]

This is what I have done so far, may of gone too far but every thing still
appears to be working.
I have not touched any Aquabanking stuff, not sure what needs to be done to
get that enabled but probably would not take long to convert.

All glade files are now verified against 3.10 and deprecated widgets
changed.
Stock buttons changed to the equivalent labels and images changed to icons
including the GNC_ ones.

All deprecated widgets have been changed to 3.10 equivalents apart from
GtkUiManager, GtkAction and GtkActionMenu. These are mostly to do with
toolbars, menus, accelerator keys and there are no easy real equivalents so
propose to leave them deprecated to the end and then maybe a decision can
be made.

I have tried to stay away from the register but some of the commits have
replaced some deprecated widgets.

I have experimented with some CSS by adding style context classes of the
nature "GncImapDialog" to various dialogues and this seems to work quite
well down to changing the background colour of different tree views. May
continue to add more.

There are no doubt some tweaks to be made to align with current version but
maybe that should wait till the gtk3 branch is updated from master.

With version 3.22, I am getting warnings on the console about transient
windows not having a parent so may have a look at that next. There are
other warnings but they seem to be concerned with GTK itself, may need
looking at, not sure. Also with this version we get a whole new set of
deprecated widgets that may be an idea to get replaced. Will need to do a
complete rebuild on this version to get an updated log file.
