[Pharo-dev] Updates for Pharo4

I’ve opened an issue with a slice for integration. https://pharo.fogbugz.com/f/cases/14159/Update-Fuel

I fixed a couple of issues and failing tests for Pharo4. There’s also a couple of new things (e.g. test cases for Context instead of MethodContext) that should be integrated into Pharo4.

Cheers, Max
