A TDD test to check we can set the theme from a user-defined stylesheet. For this, just use Solarized_Light2.
... with their own custom stylesheet. At the moment this must be called 'user.mplstyle' in the cwd.
Follows on from matplotlib#2 and matplotlib#86. We can remove the hard-coded theme setup and move to using matplotlib stylesheets (napari-dark.mplstyle and napari-light.mplstyle) instead. The caveat is that this means the plugin is _less_ flexible when presented with a weird and wonderful user theme.

There was a problem hiding this comment.
Here is where we're now less flexible. I figured we should fallback to the default mpl style ☝️
We could also do something more complicated with self._theme_has_light_bg and choosing a light or dark mpl style to contrast.

A dependent draft PR (sorry!) following on from #156.
Only pay attention to 6166de7 (the previous two commits should disappear after rebasing).
Summary
We could copy the dark and light napari themes as mplstyle files and match the theme to the plot style.

Reviewer notes
We might not want to do this: it would mean that we're less flexible when a user defines their own napari theme (the previous way, of interrogating the
napari.themeto manually set plot style was agnostic to whether the napari theme was stock or custom).On the plus side: the code is simpler, and it separates aesthetics from function.
