Several minor FindBoost changes to address posts on mailing list 

1. Add STATUS output "Could NOT find Boost" if boost is not found
which brings FindBoost closer in behavior to most CMake find modules.

2. Add an option: Boost_DETAILED_FAILURE_MSG to output
Boost_ERROR_REASON on a non-REQUIRED find if this
is desired by the developer.  This is done because the error messages
are rather long and software with optional Boost dependencies might
not like them showing up by default, especially since this wasn't done
before.

3. Add mention of Boost_ADDITIONAL_VERSIONS close to top
of file since this seems to be the most common problem brought
up on the mailing list (maybe people will notice it there)

4. Added additional check for intel compiler which probably isn't
necessary but ultimately should be cleaner if CMAKE_CXX_COMPILER_ID
sticks around.

5. Added my name to the Copyright list
