Add /trees which serves the contents of a git tree using ls-tree.

/trees queries take repo URI, a SHA1 ref and an optional path parameter.
The result is a JSON dictionary of the form

    {
       "repo": "<repo URI>",
       "ref": "<SHA1 ref>",
       "tree": {
            "filename1": {
               "mode": "100644",
               "kind": "blob",
               "sha1": "FOOBARBAZ"
            },
            ...
        }
    }
