js2-mode is included in the repo for development and CI purposes. I want to
test in a clean environment (emacs -Q) and also on Travis CI. Having that
file available lets me easily add it to the load path. I do exclude it in
.elpaignore, because I expect that when context-coloring is installed, the
package manager will handle the dependency instead.

Yes, it is a truer statement that (in its current state) context-coloring
works fine for some modes, but requires those files for non-js2-mode
JavaScript modes.
