Fix issues related to static/gulp generator files

[cmalven]

Fixes #145 Fixes #146

While I was fixing/testing the above, I noticed that several semi-related aspects of the generator were also broken:

• globalRoute import in main.js was failing to import due to mix of ES syntaxes
• Inconsistent ES style for importing/exporting modules in main.js
• Gulp and Scripts generators would sometimes fail with no deps, so I added default values for those
• Templates were using templateDist as the root dir for scripts and styles when they should have been using the rootDistPath

Fixes all of the above.
