WTD-839
Removal of 'icon-btn' class from *.html;
Cleanup of markup in switcher.html;
'name' span is now hidden when switcher is within frame;
Commented out unused css classes in _controls.scss,
Normalization of markup in object header when in main view and framed objects;
Icon sizing fixed in menus and switcher control;

WTD-839
Refactoring in advance of style mods to switcher when in frame;
Moved btn styles from _controls.scss to _buttons.scss;
Markup cleaned up with css classing simplified;
Fix usages of the plot updater, introduced to track real-time
telemetry to remove the need to cache values elsewhere. This
allows memory usage to be decreased for WTD-751.
Restore range tick marks; these were lost in refactoring
to support multiple subplots-per-view due to a missed
occurrence of an out-of-date interface usage. WTD-625.
When changes to pan-zoom bounds are made in one
subplot, this will effect the pan-zoom bounds of
other subplots. Ensure this occurs immediately.
WTD-625.
Change plot style when in stacked plot mode, such that
plots stack as expected. (Without this change, the
gl-plot class's height of 100% will cause all plots to
fill the full vertical space, effectively acting
overlaid.) WTD-625.
Begin refactoring Plot view to support stacked plots;
separate out behavior which needs to occur per-plot
from area which should occur per-view, and add a
handler for the Overlay mode. WTD-625.
Get/set mode from the plot mode switcher; only show
the switcher if there is more than one mode available
(which should only occur when there is more than one
telemetry object in the plot.) WTD-625.
