End of the Initial C++11 Changes

A comment about the single remaining naked new and delete operations in the constant string dictionary mentioned in the last post.  An attempt was made to use a vector of standard unique pointers, but it appears that QString and QVector classes don't play nice with std::unique (or perhaps the problem is unrelated to the Qt classes).  This issue will be revisited when the dictionaries are transitioned to STL classes.

To end the initial C++11 transition, a few additional minor changes were made though there were many of them.  These included:

• Replacing all uses of the untyped NULL macro with the C++11 nullptr typed null pointer.
• Replacing tests against the untyped NULL macro with testing the pointer directly as described recently (though for QString instances, the isNull() function was required to check if the instance contained a null string, which is not the same as an empty string).
• Replacing unnamed enumerators to define integer constants with C++11 constexpr statements.
• Removing empty constructors and destructors (the compiler generates these by default).
• Moving empty constructors that have only member initializations to the header file.
• Removing unnecessary include statements (to no longer used Qt classes).
• Changing to the C++11 universal initializer list syntax throughout (except for when a specific constructor needs to be called, like giving a size to a container, or with a reference variable, which is apparently not allowed to be initialized this way).

With the conclusion of the initial C++11 changes, the cpp11 branch was merged into the develop branch and deleted.  A new branch will be created for the next set of C++11 related changes.
