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)
