    transparency: fix diasvg_import.py to read colors again
    
    This is reverting this files changes by the big commit
    Bug #591525 - Transparent objects by adding alpha to Color structure
    b8994a3489256de6baaabaf09a7cf69f39390353, which actually had two issues:
    
     - transparency in SVG is not represented by quadlets like #rrggbbaa
     - even if it would: a mismatch of the regex should have led to the
       fallback interpretation but was producing an exception instead
