React JSX included by default

[grahamdyson]

The JavaScript analyser includes support for React's JSX files. However, this support isn't turned on by default. As React is widely used with JavaScript, JSX is often used with React and that support for JSX doesn't conflict with support for other analysis, it could be turned on by default.

To have JSX on by default would require its Babel parser plugin and the ".jsx" file extension to both be added. The ".tsx" file extension could also be added when support for other TypeScript file extensions are also added (see issue #168).
