open #90
Major work in-progress on switching to .t-item-icon from
.type-icon to get item icons working better, especially
in .inspector-location in Inspector;
Significant mods to label.html;
WTD-1048
Originally did a lot of this work in warp1048 by mistake
This commit pulls in all /platform-only changes from that branch
Mods are mostly related to WTD-1046 specifically, but also touch toolbar and buttons
