Changes to the image:

- Updated the ST sources. All methods can now be recompiled.
- Added ClassBrowser2>>layout and extracted the definition from
  ClassBrowser2>>open
- Added Class>>oldRemoveMethod: that can remove a method compiled
  without namespace
- Added Refactor class with one method for now, searchInAllMethods:
  aString,
  which is horribly slow, and outputs to the console
- Added MethodNamespace>>allMethods
- Added barebones Dictionary class, based on Var

- Added (generic) Documentation class and support for class
  documentation to the browser
