Add a new method call operator, and more.

Browse Source 
The '.' operator now represents method calls. A function f: (a, b)->c
can be called as a.f(b), which is equivalent to f(a, b). Besides
this change, all reserved operators now have a negative precedence
(it's relative, remember?), and some function names were changed.
