Added a means to prevent private headers from being installed.

This fix addresses bug reports 0014698 and 0014700. Header files that were
named identically to source files were installed. The added flag allows for
a source file to be flagged with SKIP_HEADER_INSTALL, which prevents its
associated header file from being installed (thanks Ben Boeckel!).
