RLE decoder

Michael Günnewig submitted this RLE decoder to rewind... so wine can
benefit from it
Alexandre, the patch implies that the dlls/msrle32 directory is removed
and this new stuff is installed in dlls/msvideo/msrle32 instead
I think it's better to have video codecs under the dlls/msvideo dir (as
we have audio codecs under dlls/msacm)
