find a solution to share information from graphql to mdx

[axe312ger]

the context and reducer approach at the moment is problematic for SSR.

we might go for a simple map object for now, keeping the hook names to avoid breaking the api

There is actually no need to add data later on. Gatsby is very page centric, so one query per page as gatsby suggest is the best solution. All available images are then passed to mdx with a simple context without reducer.

Ahh: The solution was to simply use React.createContext
