DOS based version (purplec1.7z)
Included also to provide more details on this patch.

It patch all files (except for PixToTga source) same way as Windows version,
but using DOS engine, which require to be run from 8.3 path
(each path level must be not longer than 8.3 characters).

Thanks to Toshiba-3 for info that helped me find out 8.3 requirement.

(Windows based installer doesn't have 8.3 path limitation,
so can be run from any path).
