Parse @export/etc lines in /*comments*/ too.
Upgrade CoffeeScript to 1.6.3.

The change I care about is that single-line ### comments get output as
single-line /**/ comments, which is what linker's @keyword parser is looking
for.
Support @export in CoffeeScript.

You must declare your @exports using single-line ### comments:

   ### @export x ###
   x = 5

This involves some ugly and not 100% correct low-level source hackery, making
some assumptions about the format that CoffeeScript generates.
