Remove use of avr-libc specific ATOMIC_BLOCK, replace with a new per-architecture set of inline functions to retrieve and manipulate the global interrupt enable bit for each architecture.

Add in documentation for the USB controller common interrupt routine which must be linked to the interrupt controller in the user application on the AVR32 UC3 architecture.

Changed the XPLAINBridge software UART to use the regular CTC mode instead of the alternative CTC mode via the Input Capture register, to reduce user confusion.

Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.

Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Replace the Webserver demo's uIP with the latest code ripped from the Contiki project by Adam Dunkels.

Add DHCP server to the Webserver demo for automatic network configuration. Correct uIP timer clock not tracking the correct timespan.

Fixed lack of support for the ATMEGA32U2 in the DFU and CDC class bootloaders

Changed incomplete Webserver project over to using the uIP timer library.
