Updates the HTML docs to match changes to the Desk.com website,
including all new screenshots for the custom action workflow.
Tests four types of messages that could be sent as notifications from
Desk.com. Desk.com allows an account administrator to send any text
in a custom action, so there isn't a standard format.
Custom actions send URL-encoded POST data, the test fixtures contain
URL-encoded text like what could be sent by a custom action configured
as described in the Zulip Integrations documentation to post a new
message to a stream. (See also #2169, errors in this documentation.)
New zerver.tests.webhooks.test_deskdotcom.DeskDotComHookTests:
* Static text: minimal plain text string
* Case updated: activity alert with link to a Desk.com case and message
* Unicode text Italian: activity alert with message in Italian
* Unicode text Japanese: activity alert with message in Japanese
Each posts a new message in the deskdotcom stream.
Tested on Ubuntu 14.04. I created the fixtures with Emacs, I would
appreciate if someone can check that the Italian and Japanese messages
look ok. I used the same text for a live test and it displayed correctly.
