Maybe packagekit should be able to handle excludes.

something like get_excludes & set_excludes to read/write a list of 
exclude wildcard to the backend.

Then ignored updates can be implemented be adding the package name to 
the exclude list and reset ignored updates by removing the packagename 
from the exclude list.

but we need place to store the list of ignored updated, so we know what 
to remove from the exclude list, so it wont mess with excludes add by hand.
