I made a few enhancements to ConfigurationOfVersionner:
* allowing it to load (development version) on 2.0
* fixing it for the new Metacello bootstrap, which no longer loads the Toolbox

ConfigurationOfVersionner-SeanDeNigris.63
* Update for new Metacello bootstrap (no longer loads by default
�- Add 'Metacello Toolbox' project to baseline 1.2
�- Add 'Metacello Toolbox' as a dependency of Versionner-Core-Model
* Fix for Pharo 2.0 - Use #'development' version of 'Glamour for Versionner'
* Tiny refactor of loadWithGlamour to send #stableVersion instead of "version: #stable"
