toplevel completion

[nadako]

haxe supports toplevel completion (i think its 3.2+, but still), you just do --display Main.hx@42@toplevel and it returns a list of local vars, fields, imports, etc.

this is really important completion feature, and I'd like to see it in atom-haxe.

one thing to note: currently if we autocomplete inside function call parens, it shows call tips, but actually, i think it should show toplevel completion, and show calltips using some other keybinding (or just show both)

This is definitely in the plan :)

I've restructured the milestones for clarity, this will definitely be in 0.7.0
