Revert Embedded Mimic Size to Source Size

[du5tin]

When using embedded mimics for symbols for graphics invariably we end up in a spot where the original mimic is too small and needs to be enlarged. Without pre-planning and fore thought this creates a scenario where all the existing embedded versions of that original mimic will "shrink" in relation to new versions dragged on from the newly saved version with more stuff in it. 

Alternatively another thing that happens is different developers drag-and-drop mimic symbols onto a page and then resize them to fit creating inconsistency between pages, especially if graphics are copy and pasted between mimics. 

I propose we add a "revert to original size" option in the right-click menu on any embedded mimic object to allow users to quickly get back to what is in the original symbol.
