Breaks language-todo Highlighting Support

[evrowe]

Files of the type "Javascript with JSX" (and possibly others in the package) conflict with the native language-todo package's ability to highlight markers in comments like TODO, FIXME, etc. Not a huge issue but it makes them easier to spot in comments when they highlight properly.

This annoys me more than it should...

Ended up switching to language-babel for JSX highlighting, which correctly highlights TODOs and FIXMEs
