Fixed logic hole breaking USB operations on a USB controller with only one...

Fixed logic hole breaking USB operations on a USB controller with only one supported USB mode and no USB_DEVICE_ONLY or USB_HOST_ONLY configuration token set.

* - Core:
* - Fixed inverted LEDs_GetLEDs() function implementation for the Benito, Minimus and Arduino UNO boards
* - Fixed missing Win-32bit compatibility sections in the LUFA INF driver files (thanks to Christan Beharrell)
* - Fixed logic hole breaking USB operations on a USB controller with only one supported USB mode and no USB_DEVICE_ONLY or USB_HOST_ONLY
* configuration token set
* - Library Applications:
* - Fixed broken RESET_TOGGLES_LIBUSB_COMPAT compile time option in the AVRISP-MKII project
* - Fixed incompatibility in the CDC class bootloader on some systems (thanks to Sylvain Munaut)
