Metadata lost in trim/hold UI (dates reset, title missing)

Scenario1 : dublincore.xml file not loaded when the protocol is https i.e. insecure content cannot be displayed. Resulting in the title and presenter missing.

Scenario2 : Incorrect Date and time. Via http the metadata (i.e. title and presenter) are loaded fine but the date and time is incorrect. this is because the xml file is loaded as expected.

Resolution:
1. The dublincore.xml file should always be loaded based on the protocol.
2. the dates should be correct.

Greg please review and merge to 1.4 branch.

Merged into 1.4.x with rev 15857.
