Add more FAQ pages to the wiki

[tivervac]

The wiki has a few FAQ entries, but not all of them. I've ported some pages that are important to us from the SWT faq.

As I don't have wiki edit rights, see the patches below. You can apply them using git apply --verbose file.patch. 0001 is the first patch, 0004 the last one.

While I was working on it, I also fixed some unreadable characters and slightly improved the existing markdown.

0001-Cleanup-tofu-characters.txt
0002-Cleanup-internal-HTML.txt
0003-Cleanup-fenced-code-block.txt
0004-Add-new-FAQ-pages.txt

I think I have migrated all of them. See https://github.com/eclipse-platform/eclipse.platform/blob/master/docs/FAQ/The_Official_Eclipse_FAQs.md and its links. I also updated several of them. If something is still missing, please send PR for this repo.

Btw. I'm taking about https://wiki.eclipse.org/The_Official_Eclipse_FAQs (which I migrated). But I would also suggest to add new entries from the SWT specific entries to these documents (add to table of content and add new page.

The advantage of this format is that you can send PR without have to send manual patches.

And we should make this more discoverable... #1635

Would be awesome @tivervac if you could send PR for your SWT entries.
