Code Sharing for discussions

This adds a dPaste.com share menu, that lets you easily share a solution with the Pharo community if you need extra help

Also fixes an issue when upgrading your image and the Exercism package isn't removed

Extension Methods

This release allows students to use extension methods in exercises

Better Critics Support

Small release the improves support for running the code critic (more changes coming on this)

Full exercism packages

This is a maintenance release that promotes exercism exercises to full packages so that more Pharo tools can operate on them (method extensions - coming soon, code critic).

Also provides an easier way for mentors to load a lighter dev version to browser user submissions

Support Missing Submission ID

This release supports missing submission id's (it will refetch the id, but preserve the existing exercise)

Submit Test Results with Code

This version submits test result stats along with the code so we can better tell the status of a submitted solution

Improved Error Handling/Token reset support

This version improves error handling, allows for easier token reset and provides a top level Exercism menu.
