hyperlinks in metadata

[CarolinOdebrecht]

At the moment, hyperlinks in the meta data (e.g. project homepages) are not imported by this module. At the moment, these links are imported as strings. In ANNIS for example, it would be good to have links instead of string in the metadata. It would be great to have a kind of manipulator (not only for this module) to import hyperlinks or to have a kind of property for the SpreadsheetModule.

+1 for a general prop to convert any metadatum that looks like a URL to a hyperlink (as a global Pepper customization)
