Bugfix [#25902] alt+a over 3D view don't up date dropesheet editor

Migrating "redraws" settings from TimeLine view data to per Screen.
The options are now still shown in the TimeLine "Playback" menu
though.

This means that whatever redraw settings you set in a TimeLine editor
will be used throughout a screen (i.e. editor layout) to determine
which editors will get updated during playback, instead of only
certain editors doing certain things at vague times.

---

Also, I moved some version patches pre 2.56 version bump into a
version-check for 2.56. These must've been missed when doing the
release...
