Windows bugfixes after rebase:
- anyoption,hpp was missing #include <cinttypes>
- opentxs.cpp was missing #include <cctype>
- Moved categoryName array from opentxs.hpp to opentxs.cpp.
  It would not compile and the array initialization should
  be in the source file anyway.
Merge pull request #134 from BugFreeSoftware/Rebase_fixes
