commands: Add 'hg log --branch' and deprecate 'hg log --only-branch'

Switching to --branch makes log consistent with push/pull and make more sense
given the actual behavior of the option (you can specify -b multiple times to
include multiple branches).

This change also adds some tests for 'hg log -b'.
