Deactive mct-resize when its containing scope is destroyed;
that is, don't go on polling for size changes indefinitely.
Issue discovered/addressed in the context of investigating
sluggishness of plotting in WTD-717.
Reorganize sources for bundle platform/commonUI/general;
number of classes here has grown as a consequence of
additions for WTD-614 and so an additional layer of
organization is helpful.
Conflicts:
platform/commonUI/general/bundle.json
platform/commonUI/general/src/directives/MCTResize.js
