Adds colorization for RAML
Adds colorization for RAML

The RAML language has a handful of issues and I haven't yet been able to
identify all color combinations, but this is a good start at the majority
of useful scopes.

Some of these depend on a couple of new scopes that have not yet been
accepted upstream in the RAML plugin repository but adding them to the
Neon theme won't break anything in the meantime.
