Bastian Koppelmann dd1afe0313 Bitcell arrays: Allow mirroring on the y axis 
this allows for bitcells that need to be mirrored on the y axis, like
thin cells. However, the portdata elements also need to be mirrored on
the y axis. Otherwise the router will fail horribly when connecting
bitlines.

Bastian Koppelmann df9f351a91 Add custom cell properties to technologies 
this is technology specific database to store data about the custom
design cells. For now it only contains on which axis the bitcells are
mirrored. This is a first step to support thin cells that need to be
mirrored on the x and y axis.
