When one of the outlinks is `http://-1/` `urlcanon.whatwg` raises an
unhandled exception `ipaddress.AddressValueError` and the capture fails.
We can skip the problematic outlink and keep the rest without crashing.
`Browser.extract_outlinks` has a default `timeout=60` parm that cannot be
changed in any way. (It is always invoked using `extract_outlinks()`.
We add param `extract_outlinks_timeout=60` to `BrozzlerWorker` and
`Browser.browse_page` to allow that.
The user may set `behavior_timeout=0`. This means that they don't want
to run the behavior. As it is now, Brozzler will invoke
`brozzler.behavior_script` to load the script and `self.run_behavior`
to execute it.
We will run the behavior using `Runtime.evaluate` but then it will be
terminated immediately because of timeout=0.
It is better to skip behavior loading and running when
`behavior_timeout=0`.
Update the RethinkDB pubkey location and repo location based on their guide https://rethinkdb.com/docs/install/ubuntu/
Numpy has updated to no longer support 3.5, on 3.5, we should install a earlier version of Numpy to maintain compatibility.
Some sites don't allow you to login without clicking on a button to open a retracted modal.
This update to the login code allows Brozzler to click on all elements that we think are related to opening a login modal.
Then, if there isn't a regular form, we will attempt to fill out abnormal form schemes.
The test_try_login test has been expanded for the new type of login form we are supporting.
Add unit tests for the code that detects and tries to use login forms
automatically (`Browser.try_login`).
Add `htdocs/favicon.ico` because it is loaded automatically when the
browser tries to use the test web server and it causes a "missing"
warning.
Create a new dir `tests/htdocs/site11` which is used for login related
test html files.
