Handles for text and further elements to move them from one beat to another

As matters stand you can elements like hairpins, legato bowes and voltas let begin or end at another beat when marking their handles and move their ancre points (with keys Shift+ Left/Right or Cntr+Left/Right).
This avoids you from deleting and creating this elements anew.

It would be very useful to enable this in the same way for
- advisory texts for directing or playing equally if system text or text for a single instrument or line.
- tempo texts and indicators (bpm)
- fermata
- pedal marks
...
briefly worded everything which can be valid for a certain distance parallel to the notes and you could decide it to begin, end or happen at an earlier or later point.
