Dump all of mainpage
Make all sketches use same pinout

The Read_Infopage and Read_Mainpage should use the same pinout as the
programmer to make it possible to use all of them interchangeably.
Add prints and delay around reading info and main pages

This enables scripting better to save the data to a file, e.g.:
echo GO > /dev/ttyACM0 && cat /dev/ttyACM0 | tee info
Simplify code by sharing actions in functions

This enables a consistent behavior across all programs. Part of the work
was also to unify the pinouts used by them to avoid the need to rewire
the arduino when changing between them.
Use arduino-mk to build and install from cmdline
