Persistent Board Setting

[BADnetwork]

A great feature to add would be for each sketch to remember the board it was compiled for, if a write a sketch for a uno, it would add a file to the sketch folder with '328p, 16MHz, Bootloader' etc So when I open it next time, It auto chooses the correct 'tools' setting.

maybe it would be better if the settings were in the sketch itself in a form of a comment on first line,
or a #pragma line
that way the settings would be applied to a sketch that was copied from the internet
