[SVN] r7673 (SQL)

[Ciarán Walsh]

• If no password is stored, attempt a connection with a blank password before prompting the user. This fixes an issue which would prompt the user for a password with invalid connections (e.g. non-existent hosts).
• When attempting to store a password which already has an entry in Keychain, give an informative explanation to the user on how to fix the problem.
• For connection errors, print the error and give a link to open the configuration dialog.
