Glenn Maynard dd8d265975 Add a custom syntax to Lua, to handle command strings.

function f = cmd(a,b;c,d)

is equivalent to

 function f = function(self, ...) self:a(b); self:c(d); end

This is equivalent to LuaHelpers::ParseCommandList, except:

 - Commands are not lowercased.  Do that yourself.
 - The "parent" parameter is not included.  Use self:GetParent().
 - "+5" is not valid.

The benefits are:

 - Better syntax checking.  Running "luac" on the Lua files will do syntax
   checking, and runtime syntax checks will find problems earlier.
 - Easier optimization.  Lua files can be compiled, and when using commands
   this way, commands will be precompiled, too.
 - Commands are compiled in the same scope, so upvalues work:
   local foo = 10; y = cmd(x,foo);
