lx810l, ap2000: implement working devices
Improve Epson LX-810L and ActionPrinter 2000 up to a point where they actually work. Devices boot and enter main input loop, but input is not yet implemented. It is possible to run the printers' self test. The code has also been split from lx800.

2014-06-10 Added LX810L, gets caught in a loop almost immediately.
