== Sequencer ==

This fixes:
[#22722] Removing a sequence strip doesnt remove assosiated fcurves

by using the same hack that is used for moving curve-data along with the
strips on grab.

Should be cleaned up (both functions!) by making sequencer-strips
finally true IDs.

Until that happens, there is only an more or less ugly way of doing
that.
