Subject: [PATCH] Issue #190 & #148 - Restore tidyReleaseDate() function.

There was an idea to mark this function deprecated, such that if used the
developer would see a warning. But this was never implemented in a cross
platform way.

So for now revert to circa Jan 2015 when Jim added a build date to the
version.txt file. And now both LIBTIDY_VERSION and RELEASE_DATE macros are
established in CMakeLists.txt, and picked up in version.h.

The idea is the date will now march forward with the version number, side
by side in version.txt. Although have left tidy.c only emitting the
version on the --version command.

After this function has been marked deprecated for several release periods,
only then should consideration be given to potentially removing it.
