[11.0][FIX] web_timeline: add_events call and add jsdocs

[tarteo]

Issue: #1077

[simahawk]

@tarteo any chance to have separated commits? Makes really hard to understand where the fix is... 😉

[tarteo]

@simahawk Sorry 😄, Now it should be clear.

[simahawk]

wouldn't be better to delegate events binding to

web/web_timeline/static/src/js/timeline_renderer.js

Line 18 in a9130d5

events: _.extend({}, AbstractRenderer.prototype.events, {

?

@simahawk This PR just fixes #1077 and makes travis green (by adding documentation), I'm not trying to refactor it.

[simahawk]

@tarteo I'm not proposing a refactoring: I'm proposing to fix this in a better way 😉
Then you can tell me "is not going to work in this case" and I surrender 😄

[tarteo]

@simahawk Oh I see, I understand now. Thanks I didn't notice but of course I'll fix it the Odoo way! 👍 👍

[simahawk]

LG :)
Can you squash the last 2 commits?

[simahawk]

plus, please, prefix all commits w/ module name ;)
