continue: added support for rebase

continue: added support for rebase

This adds support of rebase to hg continue plan.

An independent continue logic for rebase is created
under continuerebase() function. For this a seperate
rebaseruntime object is created under the function to
handle an interrupted rebasestate.

Results of tests are shown.
