Add JSON and TEXT links to more pages

[GoogleCodeExporter]

Ideally, we would offer JSON and TEXT links for every view for which there is 
JSON or TEXT available. Doing this manually in the templates is easy enough but 
is surely the sort of thing we would forget to do. It might be nice to have it 
happen automatically, in which case we would need to teach BaseServlet 
implementations how to advertise which formats they support.

FWIW, this would be very helpful for the chrome team.  I recently wrote a tool 
which needed to look up commit messages (i.e. from 
https://chromium.googlesource.com/chromium/blink/+/master). I ended up writing 
a regex to parse gitiles html.

Thanks for the suggestion, we are more than happy to prioritize which JSON 
endpoints we implement first based on Chrome's priorities :)

That said this bug is specifically about the JSON and TEXT link badges you see 
at the bottom of https://chromium.googlesource.com/. Currently we *only* put 
those links on /, even though JSON and/or TEXT are available for more pages.

Having json listing for the recent commits, is the only issue (that I'm aware 
of) preventing us from moving Blink's "garden-o-matic" tool to a server:
https://code.google.com/p/chromium/codesearch#chromium/src/third_party/WebKit/To
ols/GardeningServer/scripts/svn-log.js&q=svn-log&sq=package:chromium&l=100

I looked at adding it earlier this summer, then got distracted with other 
things.  Eventually I'll get back to it.

re: #3
I don't know if this is new since your comment, but does this work for your 
json recent commits listing:
https://chromium.googlesource.com/chromium/blink/+log/HEAD~5..HEAD?format=JSON

Is it expected that the contents of these JSON links start with ]}' ?  eg to 
pick one at random: 
https://android.googlesource.com/device/ti/panda/?format=JSON contains the 
following:

]}'
{
  "name": "device/ti/panda",
  "clone_url": "https://android.googlesource.com/device/ti/panda"
}

Yes. It's there to prevent using eval. See
