Support for pandoc markdown syntax

[medwatt]

I have been using markdown to take my notes but sometimes I find myself a little bit frustrated that there are some features not supported by the github-flavoured markdown syntax. For instance, it is not possible to create a table without a header row. I don't know whether you can take a look at pandoc's markdown and make some of its syntax recognizable by your plugin.

It would be great if it supports pandoc markdown syntax. I often use pandoc to convert my notes to pdf.
