Clarify in the project documentation files what the each of the different USB AVR device "series" comprises of.

More spell checking of all source files -- correct missed errors, switch to EN-GB spelling dictionary.

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.

Fix up project documentation files' overview tables, so that multiple items occupy multiple lines in the same cell, rather than multiple cells.

Fix up demo documentation device compatibility list to be as general as possible to reduce changes required as Atmel releases more devices within the same USB AVR series.

Remove information about 64 bit Windows OS signing requirements for the CDC based demos -- apparently the native CDC driver can be installed without first disabling the OS's driver signing requirements.

Documented FAST_STREAM_TRANSFERS compile time option.

Reduced the TCP window size for the RNDIS demos (Class and LowLevel) to make them compatible with the AT90USB64x.

Move new Class Driver powered demos to a new ClassDriver subdirectory, re-add old low level demos to a LowLevel subdirectory.

Seperated out OTG, Device and Host mode demos into seperate folders for clarity. Adjusted makefiles so that the path to the LUFA library can be set in one place.

Corrections to Keyboard demo.

Removed AVRISP_Programmer project due to code quality concerns.
