fixes https://github.com/TryGhost/Toolbox/issues/150
- up until now, the test framework has copied all theme fixtures to the
test directory when it boots Ghost
- the vast majority of tests don't need all the themes, so this is quite
a wasteful operation
- this commit disables copying all themes by default, and provides the
`copyThemes` boot option to enable this
- also adds a `copySettings` option, and defaults `redirectsFile` to
false to further reduce the number of file copies

This property can be used by theme developers to determine if comments
are available for the currently logged in member. It follows the same
logic as used internally in the comments helper, so that they can be
used interchangeably

- this commit turns the Ghost repo into a monorepo so we can bring our
internal packages back in, which makes life easier when working on
Ghost
