Added new TOTAL_NUM_CONFIGURATIONS option, removed USE_SINGLE_DEVICE_CONFIGURATION compile time option (but silently convert it to USE_SINGLE_DEVICE_CONFIGURATION internally for compatibility).

Added new USE_FLASH_DESCRIPTORS compile time option. By default, descriptors can now lie in mixed memory spaces (specified by a new parameter to the CALLBACK_USB_GetDescriptor() function) unless one of the USE_*_DESCRIPTORS compile time option is specified.

   *  - Added new EEPROM and FLASH buffer versions of the Endpoint and Pipe stream functions

   *  - Dataflash_WaitWhileBusy() now always ensures that the dataflash is ready for the next command immediately after returning,
   *    no need to call Dataflash_ToggleSelectedChipCS() afterwards
   *  - Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case
+  *  - The device-mode CALLBACK_USB_GetDescriptor() function now has an extra parameter so that the memory space in which the requested
+  *    descriptor is located can be specified. This means that descriptors can now be located in multiple memory spaces within a device.

   *  <b>Fixed:</b>
   *  - Changed bootloaders to use FLASHEND rather than the existence of RAMPZ to determine if far FLASH pointers are needed to fix
