Include all of /resources/mediawiki/* in jsduck index

Not all classes/methods in these files have documention yet (the
only effective change is adding of mw.Debug), but at least the
other files are now in conforming syntax.

mw.Debug:
* Made method descriptions more consistent (a few of the "build"
  method didn't start the description with "Build").

mw.Feedback:
* There was no @class anywhere. Worked because @class was implied
  for the method name starting with a capital. It was still
  ignoring the @param tags signature for the constructor though.
  Fixed now.
