Show profile meta data in window title to improve findability/awesomebar

As a user I want to have some meta data in the window name to make finding a profile easier.

Current search result show the issue:

Goals

• Improve searchability of tabs/titles
• Quickly identify the age of profile / nightly version

Solution

The latest strawperson proposal (we can move the information bits around later when we got feedback).

Firefox 59.0.2a - Intel Mac OS X 10.13 - 2018-03-29 16:02 (public) - perf.html.

For the #929 this title would result in:

Firefox 59.0.2a Intel Mac OS X 10.13 2018-03-29 16:02 (formatting tbd, the mockup had some ideas on spacing and de-emphasizing parts)

Follow up work to be filed as polish bugs:

* Investigate shortening of OS identifiers (_Intel Mac OS X 10.13_ -> _macOS (10.13)_)

Initial idea for reference

Strawperson for naming: perf.html - [product] [version] [os] - [datetime] ([datasource])

Example: perf.html - Firefox 59.0.2 - Intel Mac OS X 10.13 - 2018-03-29 16:02:21 (public)

Moving perf.html to the back, as I usually prefer having the meaningful part of a title first. The other iteration might be a short format for the browser/os, like Firefox/59.0.2/MacOS.

Summarizing.

We can move the information bits around later when we got feedback. Everybody OK with the following first shot?

Firefox 59.0.2a - Intel Mac OS X 10.13 - 2018-03-29 16:02 (public) - perf.html.

I’d rather keep YYYY-MM-DD. 2 characters don’t make such a difference here.
