Mock Objects for C++

In ChainingMockObjectSupport.h documentation for shortcut parameter of
logic_and and logic_or is completely the same while for logic_and it must
be changed

1c1
< * @param shortcut @li true: don't evaluate \c right if \c left is \c
true (c++ standard behaviour)
---
> * @param shortcut @li true: don't evaluate \c right if \c left is \c
false (c++ standard behaviour)

The change reflects the difference between logical AND and OR, as for the
former right is not calculated if the left if false.
