Splash: add first time setup and templates to splash screen.

The first time setup screen only has the interaction preset currently, some
more work is needed to be able to set e.g. the language or compute device
here as in the mockups.

The splash screen stayed the same for now, to make room for the templates
most of the links are now in the Help menu. If there are no recent files yet
the links still show.

The splash screen buttons implementation was fully moved to Python, in the
WM_MT_splash menu.
