PharoGs Strawman 1 Phase 3: produce PharoGs image for Pharo and GemStone

[dalehenrich]

The goal of this phase is to release a pharo image that matches the functionality available in PharoGs. Ideally this would be identical to the Pharo Minimal Image, however, the expectation is that there will be some functionality in the Pharo Minimal Image that cannot/will not be implemented in PharoGs. Once a sufficient amount of functionality from the Pharo Minimal Image is functional in PharoGs, the PharoGs image can be released and developers would be expected to start developing applications against PharoGs image.
