Added queue web dialog logic to allow for multiple queue items to be selected and passed in.  (This logic currently just logs out the tags.  It does not build them yet)
Refactoring to pass multiple tags to the tag generator logic.  (but still only printing the first tag currently)
Adding the logic to properly layout multiple tags during tag generation.
Fix for bold option.  This was busted in one of the refactorings.  (time to look into unit tests for sketchup plugins.)
Re-ordering the menu commands a bit.  Putting the "settings" option at the bottom.
Fix for gcode upload issues with latest Octoprint.

Apparently the tornado server support in the latest Octoprint has issues data appearing after that last part of a multipart message.  (even though this is legal)  So I had to fix the multipart code to not include extra lines.
