New Plugin - Mixer - provides support for blockchain.info mixer direct in Electrum.

This plugin provides support for using the blockchain.info coin mixer. It's experimental and would be nice if some users could test it. 

It adds a button on the Send tab "Via Mixer" which requests a mixer address and then asks the user if they want to use it. Currently it doesn't calculate or show the fee.

It also adds a context menu item for the Receive tab allowing requesting a mixer address QR code for receiving payments, again asking if the users wants to use it.

I just through this together this evening to see if maybe people would find it useful as a stop gap until maybe a better CoinJoin or other mixer could be provided.

Feedback welcome. If interested I may add some fee calc and preview code.
