1.1.2 - Bugfix release

This fix resolves a critical regression present in 1.1.1 which prevented compiling for 24-pin parts (x07 and x17) under 1.1.1 (note also that compilation for all parts was broken in the board manager version in 1.1.0). This also contains a fix for PWM output on pin 10 (PA3) of the 14-pin parts (x04 and x14) under 1.1.1 and all previous releases, and an issue with the EESAVE configuration option for all parts except the 20-pin parts (x06 and x16) since 1.1.0.

This is the version for board manager installation.
