Bug#894757: libmypaint-common: file conflict with mypaint-data

[Jack Underwood]

Just a thought, but does the file conflict actually produce the exact same 
files?  I.e. can we just disablethese files from either mypaint-data or 
libmypaint-common (probably from mypaint-data as this lookslike the older 
package, and then have it depend on the other to ensure that those files exist 
on the system?
Then mypaint can take its own sweet time in releasing its next version :).
