Bump version for future development
Add Strutil::starts_with and ends_with, to go with the 'i' versions
SPI builds to use clang-3.4.1
CMake 3.0 compatibility:

CMAKE_CXX_COMPILER_ID may be "AppleClang" rather than "Clang" if it's the
separately versioned Apple variety on OSX. Make the test robust to either
by using MATCHES instead of STREQUAL.
