Updated some variables to be closer to the coding standards (and easier to understand).
There were a few variables in LocalConsole with single character names, and the class fields did not use the m_ prefix. I also removed a redundant variable, h. It was being set to 1 in a couple of places, and incremented in another, but never actually used.
