Moving some constants to header file. Adding them to a namespace. Eventually we'll move everything to cplodify namespace.
Changing XplodifyHandler to shared_ptr of XplodifyHandler, doing this to allow polymorphism of m_sh.
Updated thrift generated header files, nothing major here.
New thrift generated python files. No big changes here either.
XplodifyMultiHandler derives from XplodifyHandler, added logic for XplodifyMultiHandler, and some more logic for XplodifyPlaybackManager - still not great. Multisession will not work right now.
CMakeLists.txt updated for xplodify_multi_handler and xplodify_playmgr. FindThrift updated to find thrift 0.9.1 (now required).
