* We now check to make sure that the required files are on disk and
show an error message if not found.
* README updated to indicate that submodule initialisation is needed.
* Added the doxygen binaries and configuration.
* Added a `make docs` which generates documentation to the `docs` folder.
* Added some documentation to various areas of the source that I was
working with. Over time I'll be adding more and more rather than trying
to do it all in one hit.
* Refactored the kitrap0d code a bit to try to reduce code size.
As per @jlee-r7's request I've changed the output of both 32 and 64 bit
components so that the platform is included in the file name.
I also added "make clean" to the make script.
* r7_debug and r7_release configurations added.
* Make now detects if the appropriate libraries are on disk and will build
whatever it can. If PSSDK is present in the appropriate location then it
will attempt to build ext_server_sniffer.
* ext_server_sniffer is now buildable with VS 2012 with all the settings
correct.
* ext_server_sniffer was failing to load once built. The cause of this was
that the hMetSrv handle wasn't being set to a valid value prior to the
command_register calls happening, it was being set too late. I'm not
sure why this results in a crash, but moving this one call to a location
prior to the command_register calls does resolve that problem.
