New page documenting common Chunky issues

I have noticed that users ask a few common questions both here on Reddit and on the GitHub issue tracker. Instead of constantly answering the same questions I think we should collect the common mistakes and problems people encounter in one place so that they can troubleshoot the problem more efficiently.

I have added a "Troubleshooting Chunky" page to the Wiki.

Suggestions for edits are very welcome. You can make an edit via the Edit link at the bottom of the page.
