Elgg - Kaltura Plugin partnerServices3

This is the version 1.0.
Changes from Beta2:

- Changed behaviour for ajax-update, now it only checks for updated metadata from kaltura when a video is showed, solved some minor bugs related to this issue also

- Cleaned some unecessary code

- Some minor changes in the views, missing translations

- Added transparent color to rating stars instead of white background, this should help with dark Elgg themes- Improved the widget, you can now list the video-thumbnails with some description or the mini-embeded player- Changed the plugin license to GNU Public License version 3- Added a "donate" button in tools administration -> plugin settings

- Added a widget for groups showing last 5 videos
