Split todo
New example: Arithmetic
Add real-time updates
Adjust to a pure Vault API. We want to use the vault package in the future.
Remove Typable constraint from  fromAddHandler
Only relevant for Heinrich's machine: add  cabal  target to makefile.
Add missing dependencies
Switch build system to cabal only.
Retrieve resources for Asteroids example from the right locations (app bundle, cabal data director)
Add changelog
Use external vault package.
Remove remaining Typeable constraints. Bump version number.
Exorcise last remaining IORefs and replace them with Vault in the push-driven compilation scheme. (Fixes part of issue #16.)
IO actions from inside 'reactimate' may now interleave and, for better or for worse, follow the control flow of the event-based framework. This solves issue #15.
Haskell Community & Activity Report into new folder.
Minor maintenance.
Prepare 0.4.3.0 release. Remove BlackBoard from repo.
Add 'filterJust' function.
Update TODO list
Update versions of dependencies. Couldn't test process-1.1 because it doesn't compile on my machine.
