TechDraw UX Overhaul

This project will primarily change the command system for TechDraw from a pre-selection to a post-selection. So that the user can click on a command and then the feature they want to annotate. Additionally visual guidance will be added for these commands so it is natural the new post-selection. The tools that cannot be changed to post-selection will instead be grayed-out if the user has not picked a correct feature. Also the toolbars will be changed.
