Updates for windows building from sources.
Switch exec_program to execute_process to eliminate warnings.
Use WX_VERSION in CMake to form wx library names to allow using wxWidgets 3.2.x.
Added nyqstk/include headers to project so they show up in Xcode
Fix liblo handler types (patch from Steve Robbins)
Did some work on Windows. Updates to CMake, install docs, and others. Not carefully tested, but it builds now and works in Arco.
Changes to windows installer - probably just version numbering.
Got serpent and wxserpent to build (again) on Windows.
