Optimize code by replacing ^ operators

[T-Rizzle12]

While working on #75, I was looking at the pull requests submitted to the Garrysmod's GitHub repository and noticed Facepunch/garrysmod#2198. Apparently ^ is slower than * since ^ is a C call. One of the things I was focusing on while optimizing in the code was the amount of Lua to C calls. If you look at the code, you might have noticed the bot:GetTable() calls. This allows me to get the bot's Lua table which makes only ONE C call for ALL VARIABLES rather than using bot.variableName = true, which is two to three C calls FOR EACH VARIABLE. That is a lot of overhead and really slows down the game when running multiple bots. Since ^ is a C call to math.pow, its much faster for me to index the botTable twice and multiply it rather than run ^.

TLDR; ^ is a C call that makes the code slower and variableName * variableName is much faster which is important for this addon.

Indeed, that was part of my concern.

A small correction though, I wasn't exactly saying ^ was slow because it was a C call, but because it was a C call to the pow function, which is not suited for small constant exponants. :)

Ok, in this addon, the code only really uses ^2, so I wonder if this addon would see considerable improvement.

I'm going to put this on hold since recent benchmarking results show that its slower to use * over ^. It depends on whether there is a performance improvement or not.
