Plugins:

- display author and and author url (if present) on plugin admin page - uniformized versions/authors... for all plugins in svn - security fix (html escape name, version, uri, author... to avoid javascript injection which could automatically simulate click on Install) - added confirmation for install/uninstall plugins Web services: - web service explorer now caches method details in order to avoid unnecessary web calls - web service explorer can now send parameters as arrays - web service explorer uses now prototype.js version 1.5 - small improvements - added and use function bad_request (sends http status code 400) git-svn-id: http://piwigo.org/svn/trunk@1852 68402e56-0260-453c-a942-63ccdbb3a9ee
