* Finds the paths on the disk where Steam is installed and where games are
located. (Uses the Registry on Windows, and maptransfer.cfg for other OSs)
* BZips the Map before upload, and only uploads the BZ2ed file. That way,
maps are automatically prepared for fast download, while saving (mega)bytes
for the client to upload.
* Uploads .nav/.txt/.res files, if any.
* Hardlinks files on the server side, if more than one gameserver path is
specified in the config; that way a single map is uploaded to multiple
servers at once (and only takes up the space once, too).
* Saves you and your users a lot of tedious cdery and copypasta.
* Highlights the maps you or the server don't have, so you easily see what's
missing on either side.
