Replace EDAM layer with miniEDAM and newer Thrift modules.
The new miniEDAM is much thinner, with one disadvantage: the primitive typed fields are now
accessible as NSNumbers instead of as primitives. Comments in the declarations indicate the
true type.

I removed support for the upload/download progress metering for now since the
EDAMNoteStoreClient no longer exposes its transports. I'll figure out how to restore this.
