The previous default name was "exports.parser". This meant that to use
the generated parser in Node.js, you had to use code like this:
var parser = require("./my-cool-parser").parser;
parser.parse(...);
Now you can shorten it a bit:
var parser = require("./my-cool-parser");
parser.parse(...);
The shorter version makes sense since no other objects except the parser
are exported from the module.
Similar issue exists on Windows too (they have symlinks since Vista), but I
could not find how to dereference symlinks from batch files, so I did not fix
it. I guess this does not matter much given how little the symlinks are used in
the Windows world.
Closes#1.
