Thilo Schulz 813a6ecdc3 - Fix bug that allows a malicious server to write and overwrite any files in the quake3 directory. 
Reported by Luigi Auriemma.
- Moved directory traversal check to a more proper location.
- Added a few sanity checks for checksum/pakname storage to fix a crash that can occur under certain circumstances.
