This restores the hidden maps from the Remaster (which were from the id Software FTP) due to size constraints and also adds 2 old FTP maps from the id Servers that were left out, in total, 5 new maps are added, those being:
base64 - The Stroggos Base
city64 - Courts at War
sewer64 - The Sewers of Stroggos
q2ctf4a - Outlands II (The original one was renamed to Outlands, probably has no bot support)
match1 - Reckless Abandon (A remake of a "The Abandoned Place" for Quake 2, no bot support)

Just place pak1.pak in the baseq2 directory (rerelease/baseq2) and run the game. Create a match and they should appear in their categories.

Not sure if this is the right way to do it yet, but it seemed like the best one so hell, why not?
