Associativity of member expressions is incorrect

[tobil4sk]

Right now, nested member expressions are parsed incorrectly.

a.b.c;
/*
is parsed as:
(module
  (member_expression
    (identifier)
    (member_expression (identifier) (identifier))
  )
)

---
instead of:

(module
  (member_expression
    (member_expression (identifier) (identifier))
    (identifier)
  )
)
*/

The second one is the correct interpretation. This can be verified by added parentheses to the expression:

(a.b).c; // this is valid haxe
a.(b.c); // this is invalid haxe

Solving this would also fix this problem:
