Fixes & workarounds to compile on Nim 2.0.0

* Import punycode, as it has been removed from stdlib.
* Fix some syntax errors
* Apparently you can no longer compare distinct pointers with nil.
  Add explicit comparisons with typeof(nil) instead.
* htmlparser: rename _ to other, as semantics of _ have changed.
  (Quite a shame, it looked better with _. Oh well.)
* Explicitly specify mm:refc, as the browser OOMs with orc for
  some reason.

Confirmed to compile & run on 2.0.0, 1.6.14, 1.6.12, 1.6.10 and 1.6.8.
(<1.6.8 it's broken & wontfix.)
