Library change

I have just split the utf8proc library out from the NetSurf utils directory into a core conveniance library (libutf8proc). The only impact this will have for most of us is that the env.sh script should be updated to the latest one and "ns-clone; ns-pull-install" run before trying to build netsurf itself. The new libutf8proc library [1] is a simple checkin of the 1.1.6 public software group library converted to use the core library build system. There is one additional change added which exposes the normalise capability of the library. In future this should allow us to update this library to new upstream releases with a clear separation from the main NetSurf codebase.
