Add class cmRST to do basic reStructuredText processing
Create a cmRST class to perform just enough reStructuredText processing to support display of Help documents in human-readable text format. This will be used to implement --help-* command-line options. Support directives "include", "replace", "parsed-literal", "toctree" (Sphinx), and "cmake-module" (CMake Sphinx Extension to scan .cmake modules). Support inline CMake Sphinx Domain roles to convert cross-references to corresponding title text. Support inline substitutions defined by the "replace" directive, but keep it simple by requiring replacements to be defined before use. Add a CMakeLib "testRST" case to cover processing of supported constructs and compare results against expected output.
