disabled BuildShortPathName
calls should go through vfsCleanFileName (which changes to lowercase and 
changes '\\' into '/' for everything).
it seems to works fine on most things, except the project needs to be 
regenerated (to get long filenames in there)
it is still possible than vfsExtractBasePath would be broken because of this, 
or that some old maps would not load the .md3 very well
but leaving the short path names field is an imperative, so we'll have to bear 
with it..

leaving this bug open because it probably requires some testing, and changing 
the binary to force load a new qe3? (see qe4 project versioning bug)
