changing syntax of member functions

[aep]

i'm going to change the syntax of member functions.

they're currently associated by being in the same module, but i think the way golang does it is simpler.

current style:

struct Foo {}

fn foo(Foo *self, int bla) {}

new style:

struct Foo {}

fn(Foo *self) foo (int bla) {}

this might also fix #123

@jwerle objections?

No objections from me!

ah well, not as easy as i thought.

this requires solving the problem that right now absolute names have to be exactly 3 parts long, project::module::type.
since you'd nest the functions inside the type, it's project::module::type::type, but abs can't do that.

changing the syntax - without actually allowing multiple functions named the same way in a module - really doesn't add much.

too much work for now.
