histedit: removing the experimental config 'histeditng'
This config has been around for about 2 years now. So, it can be
assumed to be stable. Therefore, I am removing the config. This also makes the
test 'test-histedit-base.t' compatible with chg.
Test Plan:
- Ran the test 'test-histedit-base.t' with and without '--chg' option.
- Ran all the other tests without '--chg' option.
- Checked the output of 'hg help histedit'.
