Code re-organization and comments
Clean up the constructor regex and a bit more code reorganization

Put just the Rails engine require in a conditional instead of the
entire file. This will make testing easier when I actually write some :)
Revert back to more greedy constructor regex
Minor comment & code quality improvements
More comments
Use max z-index for box positioning
No longer necessary to use JSONP when opening files
Show the file extension on layous in Xray bar
Conditionally use skim comment syntax for injecting html comments into JSTs
Use a regex when checking for skim in augment_template
Cleaned up regexes and spaces in comment parsing

Code clarity changes to xray.js
Add specs
