• Add quest::commify(number) to Perl.
• Add eq.commify(number) to Lua.

The rename is a bit needless. You can overload types in C so we could have two commify with different type inputs for both string and numbers

I only renamed it because when I had the questmgr and string_util method named the same it immediately crashed and I got an access violation.

You can access commify string util directly from within the lua / perl calls and skip creating a quest manager wrapper function
