FindBISON: Fix bison++ version parsing to avoid "Offending entry"
I've just found out that use of FindBISON.cmake shipped with CMake 2.8
on system where bison++ is default bison executable (e.g. Debian Linux)
will result in corrupted CMakeCache.txt file and parse error due to
"Offending entry"
As FindBISON.cmake logic used to obtain installed bison executable
version is tailored to match only the message used in GNU Bison it fails
on absolutely different Bison++ version message and whole version
message including \n characters is stored into BISON_VERSION which is
then dumped into CMakeCache.txt, so everything after first \n character
makes "Offending entry".
