Support for primitive (non-Object) captors in littlemock

The LittleMock captor does not support primitive types
such as int -- the respective code crashes with a

This CL implements an approach for avoiding this problem
in a way that stays as close to Mockito syntax as possible:

- the generic capture() works for primitives as well;

- we create the ArgumentCaptor with the same basic approach
  as Mockito does it, from a class object of type T:

  <T> ArgumentCaptor<T> LittleMock.createCaptor(Class<T> clazz)

  ( Mockito uses ArgumentCaptor.forClass(Class<T> clazz) )
