[Bf-funboard] Loading Screen for Blender

[Diego Gangl]

Hi all,

Blender loads pretty fast for me on factory settings, but once you
start piling addons it takes longer and longer. As addons become
larger, startup (registration) times will increase too.

I don't know if there's much Blender devs can do to improve this,
since it's third party code.

Maybe it would be useful to have a splash screen that only shows up
after X seconds of loading. It could be just the Blender logo and a
text like "Loading addons..." so the user gets a hint.

Cheers!
