LF2 Arena (Open Sourced)

[mfc]

well we tested the Arena and we found out something freakly strange you didn't mention about:

at first it worked fine, but after a few second lf2 became slower and in the end it lag-to-DC.
other functions we didn't test(or i don't know if they've been tested yet).

what is this situation?

I see. Arena needs to be rewritten. I will rewrite it again with a shiny and more secure code.
But I have other stuff to do:/
