Issue 1720: Recompile on a class should only recompile that class, not the whole image

pharo1.0-10502-rc1web09.12.2

Class browser used (if applicable): OBSystemBrowserAdaptor

Steps to reproduce:
1.Middle click on any class
2.select refactor, recompile
3. alt-.

ORCmdRecompile execute
        OBWaitRequest block: [
                self environment classesAndSelectorsDo: [ :class :selector
|
                        class recompile: selector from: class ] ]

where self environment = Smalltalk

Surely it should only recompile the class we clicked on.
