Add searching for named branches
named branching is when you identify a head by a tag on an earlier revision.
This patch adds repo.branchlookup for searching through the tree to
find branch tags for heads.
hg update -b tag is added to checkout based on branch tags
hg heads -b is added to print the tag associated with each head
