Add extra datatype integrity test

For https://tickets.puppetlabs.com/browse/RAZOR-135
Add "lower" & "upper" matcher functions

To facilitate case-insensitive string matching for instances like MAC addresses, functions "lower" and "upper" have been added to the matching language. This will allow, e.g. `["=", ["upper", ["fact", "macaddress"]], "F0:1F:AF:D8:F2:A6"]`

Fixing stock tasks

Some stock tasks required fixing due to the migration from RAZOR-154. This file movement means the user does not need to rename any tasks.
Link repo to task

The association between a repo and a task should not be indirect through the policy. Repo requires an association to task. Policy has an optional association to task, which will help with backward-compatibility.

Razor version string must not include a newline

An undetected bug meant that some razor versions could include a newline when
generating from git metadata.  This hadn't caused any practical problems until
we started using that as part of the etag for cache control.

This fixes the issue, and adds a test to try and catch this if it crops up
again somewhere.

Add generated help text to the command data

Now that we have a basic protocol for fetching data about commands, we can use
that to expose the documentation added to them to the world.  This commit adds
the basic infrastructure for rendering help text as markdown, and wires it up
to the public API.

Implement a basic full help template

This adds a basic template to cover the help output, and extends our help DSL
to cover a few more details that this showed we needed.  This is hardly
optimal, but is a reasonable starting point for rendering the help text
for our commands.
