javascript: update Events, misc fixes & additions

Events: just implement the interfaces, no events are triggered yet.

JS changes:
* add LegacyUnforgeable
* make consts enumerable
* fix crash in isInstanceOf
* fix destructor warnings
* refactor registerType

As a result, peakmem is now 1G+ on 1.6.14. It stays ~750M on 2.0.0. Hmm.
Well, better upgrade to 2.0.0 I guess.
