Add support for wiki links
Additionally support for pipe syntax for link description would be a nice addition. An option to switch the description and link order can be provided since some implementations (like Creole, Github Wiki) use the reverse order.
Unfortunately, if you have set conceallevel = 2 (which I prefer to just syntax highlighting), those wiki links completely disappear.
execute 'syn region mkdWikiLink matchgroup=mkdDelimiter start="\[\[" end="\]\]" contained oneline' . s:concealends
fixes this, (notice concealends instead of conceal) fixes this, but I have no idea what I'm doing.
Perhaps it also makes sense to give wikilinks another highlight group as they tend to be "internal" links. I have chosen "Identifier" for now.
See my branch for those changes: https://github.com/geier/vim-markdown/tree/pr/478
