Kind of a side deal

Do not use this release; it's quite broken. Left online for records only.

This is, probably, hopefully, the last release I'll make with JS code in it. It's very much stripped down: no "accounts", no prompt commands (other than exit), no CPU mining. Check the README and set your configuration in 0xbitcoin.json.

This release supports multiple GPUs and has (tested!) UI code for Windows 8 and earlier, as well as for operating systems that properly support ANSI/DEC control codes.

There is now a dev fee. Further details are contained in the README, and the code is quite simple.

Linux version is built from commit 18ee481, which solves several Linux-specific build errors.
