abort: added support for evolve to hg abort
This patch adds support of `hg evolve --abort` to `hg abort`
plan.
This involves creating a `hgabortevolve()` function under
`evolvecmd` which ensures abortion of evolve via `hg abort`.
This function is then registered using `addunfinished()` in
`__init__.py`.
Results are shown as tests.
