Generate a win32 .exe for automatic patching

[johnr14]

1. Make builder generate a .exe with gui that will ask for the ORI directory to be patched, incorporating the data in the executable, with integrity check,
2. Include a .nfo, image .png and .ico for the gui with a link to your site for donation :)
3. generate a dot(.)backup directory with a copy of the old files before patching (a revert back function :),
4. check if files are missing/wrong version before patching (and sha2?)
5. show a progressbar with time approximation.
6. It should be possible to extract the data from the .exe so it can be used on an incompatible system (ie linux/mac)

Do you think it could be possible without too mutch work ?
Thanks
