fixed TIMER4 use on Leonardo
...
ATMEGA32U4 has major differences in TIMER4 registers compared to ATMEGA1280 and 2560. turnOffPWM, analogWrite, and initialize routines had wrong registers, bit names, etc.

Improving third-party hardware support:
...
- moving back to multple cores per platform
- using target instead of platform
- moving per-board and per-programmer preferences out of Preferences.java and into a new Target class
- adding a new "target" preference
- support for platform:value values in board preferences for bootloader path and core
- XXX: need to support platform:value syntax for board upload.using preferences.
