Add gittattributes file with JSX syntax highlighting activated

Activates JSX highlighting for *.js files. Normally only *.jsx files are syntax-highlighted as JSX by GitHub, but with this change all the files will be.

If the file doesn't contain JSX, it'll be highlighted just like any regular JS file.
