Improve Vue support

[jasonLaster]

Description:

This is a tracking issue since recently I've looked at a couple of Vue apps and am seeing similar things

• Source files do not map to the source tree
• There are 5 Vue files for every one good one. We should do a better job of hiding the unnecessary ones
• We could do a better job of source mapping expressions
