Added reserved word conflict prevention in Google's Closure Compiler

[caseywebdev]

(and possibly other parsers too)

Go to http://closure-compiler.appspot.com/home and enter var ac = a.class; to see what I mean.

why not just use the string in each spot? a['class'] etc is a bit nicer than using the var IMO, after that I'll merge

[caseywebdev]

I assumed Google Closure (Uglify does this) would convert klass = 'class' to a = 'class' and then save bytes by replacing all of the b[klass] with b[a], but it looks like GC substitutes the string where the variable was. I wonder if initializing strings is faster than variable lookups?

[tj]

faster here is really irrelevant, for several reasons but even without a JIT it's a tiny tiny tiny tiny micro-optimization

[caseywebdev]

So how small is the optimization? =p

Thanks for the quick merge!

[tj]

way too small to care about at all ever :p
