Normalize vim-javascript syntax highlighting

Use orange for actual definition (not invocation) of function names or
method names. Use blue for keywords such as 'function' and 'class'.
Finally, use cyan for actual class names. This limits the use of orange
to the actual names of functions/methonds at their definition site.
