add miscellaneous event to browser window callback table

extend the browser window callback table with a miscallaneous event
 entry. This is used to replace all browser window callbacks which
 take no parameters.

This reduces the API surface from seven separate calls to a single
 call with an enumeration which may be readily extended.

The initial implementation in the frontends simply calls the original
 implementations to reduce scope for errors.
