[PCB] What to use for ceramic capacitors?

Nevermind. found this:

• lib/geda.inc: - remove the BRE* footprints. The required PKG_RECTANGULAR macro doesn't exist anywhere and I can't figure out what the correct behaviour should be anyway so rather than propagate a very questionable footprint name, kill it right here. - Fix the problem where the ACY*P and RCY*P packages called non-existant macros. They now produce the same footprints as the ACY* and RCY* packages but with a polarity marking. The suitability for any particular part number should be still verified before using them on a board.
