Add support for Webhook note events

This MR adds support for note events (comments) for WebHooks.

Perhaps the only potential source of confusion is that the settings indicates "Note Events" instead of "Comments". What do you think?

Use the user list from the target project in a merge request

### What does this MR do?

This MR derives the assignable users from the target project.

### Why was this MR needed?

In a merge request, the assignable users uses the list from the forked project, not the target project where the merge request will be going. For example, if I fork a project from the gitlab-org namespace into my personal namespace, make some changes, and then create a merge request, the only users I see are me. I think it makes more sense to show all the users in gitlab-org. This is a regression caused by 1c2711f7.

### What are the relevant issue numbers?

Closes #1535

Changing your time zone

Added doc and link in workflow to how to change your time zone in Gitlab.

I used the following documents as reference. Please double check that the instructions I wrote are correct.

I found that several users have this same issue, that they don't know how to change their time zone:

Work around a Chrome 43 bug preventing note editing

Fixes #1568 - and I mean "fixes"

I have no idea what causes this or why this fixes it and can't dig into it further right now, but the bug seems like a blocker so this needs to be fixed for 7.11.
