subrepos we have.

dashboard/env: update watcher Dockerfile to use latest version

This version includes the JSON polling from:
   https://go-review.googlesource.com/#/c/1568/

Also, we no longer need sid because we no longer need Mercurial,
so revert back to wheezy, which is less of a moving target.

cmd/tipgodoc: make tipgodoc run on App Engine Managed VMs

At least in theory. We don't totally have it working yet. It does
run locally in the dev environment, though, which should be the same
as production, since it builds the Docker container locally.
But we're getting problems when pushing it to production.

Also some minor tweaks to the code with Andrew.

dashboard/builder: remove the repo export speed hack for hg

The builder will no longer generate a VERSION file, so we
can revert https://golang.org/cl/1405 once all builders
have updated.

Fixes golang/go#9296.

Also add support for /cl/ID/, because go commit 0edafefc36 uses this
form.

stringer: avoid if's in the generated code

Suggestion by dsymonds: Save code not data.
Add an extra element to the index array and an if can be eliminated.

Old generated code:
const _Day_name = "MondayTuesdayWednesdayThursdayFridaySaturdaySunday"

var _Day_index = [...]uint8{6, 13, 22, 30, 36, 44, 50}

func (i Day) String() string {
	if i < 0 || i >= Day(len(_Day_index)) {
		return fmt.Sprintf("Day(%d)", i)
	}
	hi := _Day_index[i]
	lo := uint8(0)
	if i > 0 {
		lo = _Day_index[i-1]
	}
	return _Day_name[lo:hi]
}

New generated code:
const _Day_name = "MondayTuesdayWednesdayThursdayFridaySaturdaySunday"

var _Day_index = [...]uint8{0, 6, 13, 22, 30, 36, 44, 50}

func (i Day) String() string {
	if i < 0 || i+1 >= Day(len(_Day_index)) {
		return fmt.Sprintf("Day(%d)", i)
	}
	return _Day_name[_Day_index[i]:_Day_index[i+1]]
