Merge pull request #42 from andyseubert/master

Add a Bike Light program extending Functional and taking from Tactical.
added new boards.txt for Arduino 1.5 compatibility. Thanks to Josh Goebel (github: yyyc514)
Add new program that is similar to up_n_down

Similar to up_n_down, but adjustment of the light only happens when
button is held, not when it is first turned on, so the saved brightness
is used. Holding the button while on set the brightness and then it is
used until reset again.
Near final change to the new program

Added code to detect if the EEPROM has ever been initialized and
initialize it if it has not.
Update comments and minor changes

Fix some spelling errors and other minor things in the README.
