Meshmoon Linux: Add minimal boost build to satisfy websocketpp.
Meshmoon Linux: Add installer dest dir to .gitignore.
FindBoost: Make library set to find customizable. Done in TUNDRA_NO_BOOST mode from WebSocketServerModule (todo vefiry windows).
WebSocketServerModule: Define only boost system to be needed on linux. Defined websocketpp C++11 flag if enabled in Tundra.
WebSocketServerModule: Dont include boost in Tundra code and do not do internal typedefs with boost::shared_ptr. This fixes the build on Linux with boost 1.55 but has to be tested on Windows before done there. So todo: check if this builds on windows and remove the ifdefs.
Meshmoon Linux: -p to build script will also build the .deb package.
