Before, the UMSELn1 bit was being to set to 1, putting the UART into a reserved mode. Now, we only set the high (0x80) bit to 1 for the ATmega8, which is needed to access UCSRnC (whose i/o address is shared with UBRRH).
Also, no longer bitwise-or the new config with the existing register value, because we're actually configuring all the settings in the register. (We're not using UCPOL, but it's supposed to be 0 in asynchronous mode.)
Mostly useful for Leonardo - simple way to test whether the port is actually opened by an application and ready to receive data. For Serial objects attached to real UARTs always returns true.

- 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.
Compilation still has problems (Thread error on success, and can't handle non-pde files in a sketch).
Modified the Mac OS X make.sh to copy the hardware, avr tools, and example over.
Removing some of the antlr stuff.
Disabling the Commander (command-line execution) for now.
Added Library, LibraryManager, and Target.
Added support for prefixed preferences (e.g. for boards and programmers).
