Fixed fooprint + LED + shrunk

The MCP1804 is quite a good regulator, very low standby consumption, smaller footprint too. So I switched to that and shrunk the board by 2mm. Can't make it much smaller without moving to insanely small parts.

Code and design files.

Let's see how long I have to wait this time. On the positive side, OSHPARK shouldn't be affected by this year's Chinese New Year (10. and 11. Febr. 2013) and the accompanying celebrations.
