Strange behavior of metadata lookup button in Document Properties dialog

[Alexey Balmashnov]

The "Look up..." button is always turned on.

Although, if I understand it correctly, this button should be enabled, when url to look for a document metadata is already assigned (available), or such data is being entered in the dialog.

Referencer 1.0.4 and svn rev 542 are affected

Patch is the right idea, but needs a couple of changes:
 - DOI isn't the only way to get metadata, there's also eprint, which is considered an "extra field". So sensitivity also needs updating on adding, removing or editing an extra field, and the update needs to check whether the eprint field is present.
 - In update(), canWebLink should be canGetMetadata

Cheers,
John

Marking confirmed, on the basis that the "Look up..." button really shouldn't be sensitive when it's non-functional.

Ok. It works now. Hope, I did not miss anything.

I've (eventually!) committed this to subversion.
