Vanilla authenticator

[pscott]

As per what was described in milestone1, here is a vanilla authenticator contract that does not check any signature and only forwards the call.

looks good

Tests are failing because we need to define the SPACE_CONTRACT if we wish to interact with it :p But at least we've got the code required to interact with the authenticator contracts (useful for @bonustrack :))

I suggest merging this bad boy (I commented out the tests for the vanilla auth), so that I can then merge develop into the other branch (vanilla_space). Since both branches need each other, I think it's the only way :) (or we could directly merge this branch in vanilla_space) but I think it's cleaner to merge this one into develop first. @bonustrack wdyt? :)

Sound good!
