Check for solid when exporting

[Scott216]

I have a suggestion for a feature - when exporting an STL, check to see if the object is a solid. If not, let the user know. I frequently run into problems printing STL on my 3D printer when it's not a solid. I try to remember to check, but sometimes forget.

I like the idea. The Importer already has an option to check and heal geometry after importing. It seems like a good idea to be able to perform the check and heal before exporting to improve the quality of the exported file.

There could be a "Solid Check" option on the exporter dialog.

I'm adding this to the 2.2 milestone.
