histedit: make histedit's commands accept revsets (issue5746)

Earlier the code was only looking for rulehashes and neglecting
all other revision identifiers, this code intercepts the fromrule function
and calls scmutil.revsingle() on anything that is not a rulehash and then
obtains the rulehash from the changectx object returned, rest of the pipeline
follows as it was
