Bug fix changes

The following MDT-OCL 3.0.0 bug fixes obviously change behaviour slightly.

Bug fix Related bug/s Owner Adopting Milestone
Give if atomic precedence 184048 EDW M3
Fix Integer Dot parsing 288601 EDW M3

Environment changes

Bug fix Cause Related bug/s Adopting Milestone
Remove EModelElement inheritance of EObject:

this prevents use of eContainer() and eContents()

EMF 2.6.0M4 255469 M4
Change UMLReflection.getContainerElement() return to List<? extends EObject>

this avoids a (valid) compilation warning

JDT 3.6.0M4 298128 M6
