route: prepare to fix routing of hierarchical branch names

Branch names in Git may be hierarchical (for example, "wip/parser/fix"),
however, git-arr does not take this into account in its Bottle routing
rules.

Unfortunately, when updated to recognize hierarchical branch names, the
rules become ambiguous in their present order since Bottle matches them
in the order registered. The ambiguity results in incorrect matches. For
instance, branch pages (/r/<repo>/b/<bname>/) are matched before tree
pages (/r/<repo>/b/<bname>/t/), however, when branch names can be
hierarchical, a tree path such as "/r/proj/b/branch/t/" also looks like
a branch named "branch/t", and thus undesirably matches the branch rule
rather than the tree rule. This problem can be resolved by adjusting the
order of rules.

Therefore, re-order the rules from most to least specific as a
preparatory step prior to actually fixing them to accept hierarchical
branch names. This is a purely textual relocation.  No functional
changes intended.
