[CDE-371] - Add support for Require js in CDE
	- Reviewed Mustache usage, deprecated 'compile' function
	- Reviewed CDF resources paths
	- Set default wcdf require tag value to false so legacy dashboards can be rendered correctly
	- Changed cdf.resources.base.url in build.properties to use "api/repos" instead of "content" because JS resources were being loaded with the string "Unable to render dashboard"
