cmake: Add ENABLE_SHARED option, default ON

Add an ENABLE_SHARED option, defaults to ON, when set to OFF
quassel_add_module() will build modules as static (does not affect
platforms where modules would be built as static anyway.)

The option name ENABLE_SHARED is frequently used for this purpose in
cmake.
