netsurf/monkey/dispatch.c
Vincent Sanders 02bbaa3e88 split version info into its own header and remove unnecessary nesurf.h includes
The netsurf.h header should *only* contain the registration, core
initialisation and finalisation methods. Version information is best
placed in its own header.

Also remove any unneeded inclusion of this header limiting it to
solely the places the relevant API is required.
