Subject: Add CMake option FLTK_OPTION_PEN_SUPPORT (default: ON)

This option can be used to disable pen/tablet support if there are
build problems on a particular platform or build system (e.g. MinGW)
so users can continue to build FLTK 1.5.

Users can also choose to disable pen support if they don't need it.
