watching projects in Phabricator, Herald rules simplified

[Kamil Paral]

Hello everyone,

in the last week I've spent a bit of time investigating the possibilities of how to watch for ticket/revision updates in Phabricator, and found out that some new features in Phab greatly simplify this. I have updated our Phab wiki page and included most common use cases:

https://fedoraproject.org/wiki/QA/Phabricator

In a nutshell:
* you can now start "watching" projects which automatically sends you all tasks (tickets) updates. No more Herald rules needed. Unfortunately, this does not apply for revisions (patches).
* you can now easily subscribe to tickets without a project defined (usually bug reports). This way you can help us classify and triage them and make sure they go unnoticed (that unfortunately happened in the past).
* Taskotron lovers can now easily watch for all Taskotron-related new revisions (patches) by using the repos-taskotron meta-project [1]. We will make sure that this meta-project is always linked with all taskotron-related repositories, and you don't need to update your Herald rules for every new Taskotron sub-project.
* You can now easily decide between a permanent item subscription or just one-time notification by choosing either "Add emails to CC <name>" or "Send an email to <name>".

I have tested it for the last week and everything seems to work properly for me. If you have some troubles, ask.
