Some features need to take advantage of all tags to avoid reading js files multiple times

Some feature XMLs do not properly leverage the all tag in order to avoid loading javascript files multiple times when the Feature registry is populated. The ones that we can fix are listed below.

The Feature Registry reads a javascript file multiple times if the feature.xml includes it multiple times, such as in container and gadget sections.    The following files are being read multiple times according to the procmon IO Trace

features/core.json
features/exportjs
features/gadgets.json.ext
features/shindig.uri.ext

Two of the features

features/osapi/
features-extras/org.openajax.hub-2.0.5

have situations where specific files are needed by the gadget and / or the container so they cannot leverage the all tag
