Cleaner flowauth ui for permissions

[greenape]

The current FlowAuth UI for choosing API and spatial aggregation permissions is very granular and includes a lot of information, which will grow further as more API methods are added.

We should look to hide more of this information by default, on the basis that the most common usage flow is likely to be 'give me the maximum access I'm allowed'.

I'd like to preserve the level of granularity possible, but to provide a more user friendly default flow, and hide the majority of the checkboxes by default.
