Minor fixes

[xofe]

Similar to my previous PR #839, here's another handful of minor fixes for things I've noticed when working on a personal build on uMatrix. Each change is independent, so if any aren't wanted I'm happy to rebase and drop that commit.

Fixes:

• correct the cloud icon CSS selectors (FontAwesome v4.7 doesn't have the "-alt" suffix)
• fixed scope button tooltip in logger not appearing properly due to missing "tip-anchor" class
• open logger/dashboard links adjacent to current tab instead of at the end (like uBO does - makes it easier when many tabs are open)
• fix dist/version file not being used when building the Opera version (not sure if you're still updating Opera version though)
• use options_ui in Chromium manifest (from uBO - gorhill/uBlock@6dd6dc5)
• remove unused "processReferer" setting (it was changed to a matrix switch in 5d8bae3)
• remove unused profiler code (from uBO - gorhill/uBlock@f516cd3)
• remove bold version of the Roboto font (the popup currently uses only light and regular versions - removing bold reduces the size of the xpi/zip package by 75 kB)
• correct the FontAwesome license after changing back to v4.7 (it still contained the v5.0 license - I copied the v4.7 license notes from the uBO change gorhill/uBlock@bb737e2)

On a similar note, I've been using @rhendric's code cleaning changes posted in uBlockOrigin/uMatrix-issues#16 without any issues - I think they'd be worth merging in too.

Looks all good to me, thank you very much.

You're welcome!

Any thoughts on the changes in master...rhendric:cleaning (uBlockOrigin/uMatrix-issues#16)? I didn't include them in this PR as I wasn't sure if the authorship would be preserved.

The PR changed the semantic of the block count on the matrix filtering button, and I questioned that.

Looking again into it, I realize the matrix filtering button count badge is already broken anyways.

The intent was that the count reflects only what is blocked as a result of matrix filtering, not what is blocked as a result of other switches doing their work (you will notice the uMatrix icon badge differs from the matrix filtering button badge when you have referrer spoofing enabled).

But now I see it's broken anyways since resources blocked as a result of "Forbid mixed content" are reported on the matrix filtering button anyways.

So I will merge the request, keeping in mind there is still something to fix (unrelated to the PR) with regard to the matrix filtering button badge count.
