Semicolon and other style conventions. about core

Remove all der semicolons!

I'd have preferred to keep the semicolons, because I put them in automatically, being used to them from C++.
Also consider keeping parenthesis around boolean expressions, such as (a == b). They're not compulsory, but they make the code quite a bit more readable, especially in compound expressions, such as (a == b) or (c == d)

Just confirming for anyone who is reading this that convention for all new code is tabs for indentation and spaces for alignment. Also, no semicolons for plugins.

I'm eating my own words from four years ago. There's no need for semicolons in Lua, so let's let them go :)
