Apply patch from H Law about to improve MediaWiki tool :

(a) The new feature of removing metadata / geo option would not work (i.e. metadata will continue to be uploaded) IF the global option for writing metadata is set to sidecar only.  The patch rectify the issue.
(b) Use the {{Coord}} template instead of the {{Location dec}} template in the uploaded descriptions.
(c) Allow the user to override the upload comment (currently fixed to "Upload via KIPI uploader").  An additional input box is provided for the purpose.
(d) Allow an option not to provide the license part.  (Mainly for use in private wikis)
