Fixed missing description for AssumeThatInsteadOfReturn inspection.
Added new AssertThatCollectionOrMapExpression inspection that tries to pull out methods such as isEmpty() or contains() out of an actual assertThat() expression. Added more method calls that are considered extension points.
Fixed an exception in batch mode if the description string was the same but for different fixes. Now descriptions are different for quick fixes triggered by AssertThatJava8OptionalInspection and AssertThatGuavaOptionalInspection. Minor refactorings. Extended documentation.
Heavy refactoring regarding quick fixes (using more extensions).
Even more refactoring.
Fixed/extended AssertThatGuavaOptionalInspection regarding static.
imports and wrong reference to core assertThat() where Guava assertThat() actually was necessary.
