Remove context pre-processing (mostly)

This approach isn't very effective when contexts are frequently changing, and it is hard to guess in advance which contexts are going to be in-use.

The Sponge version has proven that this whole system isn't really necessary.

Contexts for 'allow all' and 'global' are still pre-processed, however this should be significantly less work for the server. (even if it is being done async)
