an options object to template().

Bug fix for template option support

I missed adding the options to the layout template function,
meaning that any options currently do not work on layout templates

Switch from glob to readdirp

Works around an issue with `glob`/`minimatch` where UNC paths are not
interpreted correctly. Using `readdirp` instead allows us to use a more
robust, simplified and asynchronous approach to loading the partials.

Fixed issue with partials not loading

Resolves an issue where partials are not loaded correctly in the event
the `options.cache` is set to `true`. Accordingly allows partials to be
loaded once, or loaded every time if caching is disabled.

In order to test both situations where caching may be on or off, we
toggle the `process.env.NODE_ENV` variable which in effect toggles the
`options.cache` parameter. Thus I have included grunt to run the same
test suite twice; once as the test suite was run before, and then again
with the environment variable set to production.
