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.

Added periodic flush timer to the Benito project. Alter the serial transmission code so that sent bytes do not block the remainder of the main program code from running.

Add new module source variables to the library core makefile, so that module sources can be added to a project's makefile on a per-module rather than per-file basis.

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 project text files to refer to "project" instead of "demo".

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.

Changed AudioOutput demos to explicitly use timer 3 - the smaller USB AVRs where timer 1 was needed instead did not have the endpoint size neccesary for good audio throughput anyway.

Fix Benito documentation indicating erronously that the project used the HID USB class instead of the CDC class.

Ensure new Benito Programmer project matches Don's established LED behaviour - flash LED while generating target /RESET pulse, ping-pong LEDs during enumeration.

Added new Benito project, a simple modified USB-to-Serial bridge for the programming of AVRs using the official Arduino bootloader.
