MDL-71614 qbank_previewquestion: Add Preview question plugin to core

Browse Source 
This implementation will introduce a qbank plugin "previewquestion"
which will view the preview question action in the question bank
actions by replacing the core classes, scripts and yui modules.
This plugin will also replace the preview option in the edit
question form. Having this plugin will give users the
flexibility of enabling or disabling this feature from
the question bank view.
This change will also allow other qbank plugins to add
elements or information in the preview question page
by implementing a callback. It also changes the pop
up to page redirect from base view page to make sure
any changes in preview reflects in the base view, for
example, comments added and the number of comments in
the comments colum changes while back from the preview
page. Other locations like edit and qtype plugins where
the preview is implemented, stays the same.
