make Shapeshift accept GRC

@grctest : "Despite Coinami's help, the continued response from ShapeShift is that Gridcoin is on a 'discovery list' and that they are not looking to add further coins in 2017, how disappointing."

• unless we get liquidity up ?
• anyways, people should contact them (tweets, email, ...) to bring attention to this

If we had ShapeShift support, it would result in being able to spend GRC on Purse.IO too.

Several new coins have been added over the last week or so, but there is no news about GRC. Should we start a "letter campaign" of some sort as a community?
