Bugfixes for recent commits:

* Insert Key on Selected Channels in Action Editor was broken
* Transform/Select All tools in Action Editor were broken as result of
filtering changes.
* Set Visibility operator, when used from Graph Editor now does
similar things to the TabKey lock/unlock operator with regards to the
flags it uses for filtering
