to be removed from the ISO krita & kexi

[Harald Sitter]

alohas,

as mentioned in the iso content review #2 thread kexi and krita cause
severe oversizing of the ISO currently, so I am going to remove both
shortly.

## Replacement
- kexi will be replaced by openoffice-base again.
- krita could get replaced by kolourpaint4 if anyone thinks that is
viable. IMHO actual raster drawing is a somewhat specific use case
that might not need to be addressed by default at all.

## Discover Features
since this was not part of the original discussion. does anyone think
either of the two applications should be added as a featured
application for muon discover?
