ClearOS Toggle Multiple Repositories at once, update contents list later

Add a tool to select and toggle multiple repositories at once

when we have to enable multiple repositories we have to do one by one and it automatically does an update on the list of contents for that server, at times taking a long time to respond and show up again on the screen, specially if your internet speed is slow. If you are going to enable or disable a few of them its nice to be able to select the ones you need and toggle all at once.
