Do not clear intro screen
Do not clear intro screen

if airline is initialized too early and some :hi commands are run,
this will force a redraw in Vim which will result in the intro screen
being cleared.

Currently, this does not work for gvim, not sure why.

closes #1476 (well only partly, until i have discovered, why for gvim it
doesn't work).
