Move the docs to Markdown Syntax

This pull request changes the documentation to the [Markdown](http://github.github.com/github-flavored-markdown/) format used by GitHub. Markdown basically looks like how most people write READMEs anyway so it's a pretty low impact change. To see what one of these reformated pages looks like take a look at [one of the files](https://github.com/igable/PerfModDash/blob/master/manuals/dataStoreOperations/01simpleCrudOperationsOnHosts.md).

The one caveat is that the files have to carry the extension md for github to parse them.
