* added operators SEQUENCER_OT_lock, unlock, reload, refresh_all, view_all, view_selected.

* sequencer transform now does overlap checks.
* removed old transform functions from sequencer_edit.c
* shuffle_seq moved to kernel, now moves strips to the end of the last sequence of itschannel (if all channels are used). 2.4x would remove the strip.
* most of the 'Strip' menu items now call their operators in the header menu, some for view and select too.
