Troubleshooting

[ranebrown]

@Nudin, @hq6 I created a troubleshooting page on the main vimwiki repository. Not sure what the best place for that is but I wanted to get the information up for people to use. We can move it to this repo or leave it there, doesn't matter to me.

I think the troubleshooting page is in a good place, if I understand @Nudin's intent for this repository correctly.
That is, this repository contains examples, but it is also for us to test features, whereas the Troubleshooting specifically targets users.
