ReleaseEngineering/How To/Update TryChooser

We need to keep the try syntax chooser webpage located here: https://build.mozilla.org/trychooser/ up to date so developers will continue to use it and we benefit from the lowered build/test load.

To keep the site up to date, check out the tools repo and update index.html with new test/talos suite names - be sure to change both the value and the label. Eg:

<li><label><input type="checkbox" name="talos_suite" value="SUITE_NAME">SUITE_NAME</label></li>

Once you've landed your patch to the webpages:

ssh build.mozilla.org
sudo su -
cd /var/www/html/trychooser/tools
hg in
hg pull -u && hg up -C

Your changes should now be live at http://trychooser.pub.build.mozilla.org/
