scm: rename JavaScript "branchGraph" function name to "revisionGraph"
"Branch" is not a common concept in the SCMs.
Mercurial "branch" has three terms. * named branch * unnamed branch (multiple heads) * big-picture branch (cloning repository)
Git "branch" is a reference to a specific revision.
It is popular that Mercurial GUI shows all revisions on the top page.
