Heads-up: krita_export.h changed to krita*_export.h in calligra/2.9

[Friedrich W. H. Kossebau]

Hi,

in preparation of https://phabricator.kde.org/D183, to reduce conflicts on 
merging from calligra/2.9 branch or future forward porting with cherry-picks, 
we... bring you possibly a few merge conflicts now to your branch/WIP against 
2.9, if you are unlucky, pardon. E.g. the animation branch might hit a few 
issues. So...

Basically where you were including "krita_export.h" before, you would include 
now
for kritaui: kritaui_export.h
for kritapsd: kritapsd_export.h
for kritaimage: kritaimage_export.h
for kritabrush: kritabrush_export.h
for kritacolor: kritacolor_export.h
for kritalibpaintop: kritapaintop_export.h

That should be all.

Cheers
Friedrich
