Order include directives alphabetically.
The google C++ style guide recommends to sort include directives alphabetically. https://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Names_and_Order_of_Includes
It would be nice if codefmt's FormatCode could also do this.
Having two partial formatters for C++ might mean people would want #44 so you could run this include sorting and clang-format on the same source code.
Discussion with clang-format owners indicate they may be willing to implement this in clang format.
Looks like clang has a sortIncludes option now. Does it sort includes how you want it automatically now, or would we need to explicitly configure something to enable it?
