Installer loops better on failure

The installer will do the following on an issue downloading the server
files in an attempt to fix the problem.
# Attempt 1-4: Standard attempt
# Attempt 5-6: Validate attempt
# Attempt 7-8: Validate, delete long name dir
# Attempt 9-10: Validate, delete long name dir, re-download SteamCMD
# Attempt 11: Failure

All goldsrc files will run a validate multiple times as well to reduce
the chance of the files not downloading due to a bug in steamCMD.

Fixed the server looping when it shouldnt
