Each symbol unit in eeschema has a unique identifier. But we don't have
a unique identifier for the entire symbol. So changing which symbol
instance was unit A (our default base for matching), changed the UUID
that we were using to match the footprints.
This commit adds all UUIDs to the netlist, allowing us to match symbol
to footprint without worrying about which unit is referenced.
This still does not handle changing different units on different sheets.

Various architecture upgrades to support this.
Creating a BOARD now requires a valid PROJECT, which caused
some (mostly transparent) changes to the Python API internals.
ADDED: Project local settings file
CHANGED: Board design settings are no longer stored in PCB file
CHANGED: Net classes are no longer stored in PCB file
CHANGED: Importing board settings now reads boards, not just projects
