Note that we cannot add a real test for onClicked without mocking out the AlertService. I did test it manually and it seems to work fine.

Also update ext-notifications.js to use a Map instead of a Set
Note that I am not sure whether the schema has been implemented exactly as we'd want. There are, for example, options in NotificationOptions that we will never use/support, so I'm not sure how to document that.

The base .eslintrc is essentially a merge of the root Toolkit .eslintrc and
the devtools .eslintrc, with some minor changes to match our prevalent style.
For the most enforces the coding styles that we've been using most
consistently. There are a couple of significant differences, though:
* The rule for opening brace alignment can only be applied globally, and
doesn't make exceptions for top-level functions. I chose to turn it on, and
change the brace style of existing top-level functions that violated it,
since the rule seemed worth using, and that's the direction most Toolkit JS
code has been headed anyway.
* The rule for switch/case statements requires an added indentation level for
case statements. Most of our switch statements did not use an extra level
of indentation, and I initially wrote the rule to enforce that style, until
I came across case statements that used blocks, and required the extra
indentation level for sanity.
