The ChatRoomView renderDragResizeHandles is only rendering the top resize handle (<div class="dragresize dragresize-top"></div>). the insert was only inserting the first child of the dragresize template, which has 3 children. Modified to insert the whole the div that the dragresize template gets inserted into.
What started as an attempt to fix a bug in parseXUserElement, turned into
another large refactoring of MUC code, and it's not clear how to break this up
into multiple atomic commits. So I'm just pushing it all.
At least there are two new tests added to the suite.
This change refactors out the plugin code from converse-core into
src/converse-puggable.js
Additionally, plugins now have an optional attribute `optional_dependencies`
which is an array of dependencies which are "nice-to-have" but not essential.
Work has also been done to ensure that a plugins' dependencies are first loaded
before the plugin itself.
