Move TeamSize config to ConVar

[spumer]

Huge updates require to fix extension. But all we do is replace one code block with another one.

I want to make possible update only gamedata. To do that we need implement few things:

• Get search pattern from gamedata (done!)
• Get patch bytes from gamedata (partial done)
• Get original code bytes size from gamedata (cause original block can be shorter or bigger than our patch)
• Introduce placeholder for TEAM_SIZE into patch, i guess it should be \x2B

After that we just need to use global var to store TEAM_SIZE and re-patch code each time when ConVar changed
