new snapshot with most electrum plugins fixed/modified to work with yac is up

list of available plugins:
* yacoin exchange rates (so far just from cryptsy api and only to btc)
* label sync
* point of sale
* qr scans
* virtual keyboard

disabled plugins:
* aliases (bitcoin electrum ships with this disabled anyway)
* coinbase buyback (for obvious reason)
