VSE: Move remove gaps operator logic to module code

Logic was broken into finding gaps and ofsetting strips.
Functions were modified so they work on explicitly defined seqbase,
so they can be used as python API functions.

Functional changes:
 - Improve performance by calculating gap length and offseting strips
   at once. Previously strips were offset by one frame.
 - Calculate gap from start frame. Previously gap was considered only
   inbetween strips.
