#2 Identify a metadata schema

[Gianni Campanile]

This patch adds an \"Identify\" buttion to the \"add resource from disk\" page. Using this button a user can check metadata record and see which schema will be selected. In addition, when using the validate and upload buttons, the selected schema will always appear, allowing the user to check wether the schema identification was correct. The caption of the button and the text of the message are in gpt.properties, so they can be customized.
