Title: fix and improve error handling

* messed up args logic at 86458b7a20fddd62206497d5edfa31dce20d0ef2 as in case of error less.js invokes `callback(error)`
* `"missing closing `}`"` should be a `ParseError` (already handled on rhino)
* make sure V8 gets the `e.value` right for the `ParseError`
* add spec for checking that *filename/line/column* work with `ParseError`
