continue: added support for unshelve

This patch adds the support for `ushelve` in `hg continue` plan.

`hgcontinueunshelve()` has been created for independent calls.
In case an interrupted unshelve is resumed via hg continue the
shelvedstate needs to be loaded seperately. This has been
ensured by `_loadunshelvedstate()`

`hgcontinueunshelve()` is then registered as `continuefunc` for state
detection API.

Results are shown as tests.
