Add support for jsx

[luthv]

Currently the snippets are only working in js files, adding "javascriptreact" in the package.json should add support for jsx files. Although for some reason we have to press ctrl+space to trigger the intellisense in jsx files while in js files the suggestion will popup immediately as you type.

In order to have these snippets available in jsx files you need to install the Reactjs code snippets. There you will also find that I have added a note about the behavior of intellisnse you described. Hopefully it will be fixed in the coming version of Code.

ah I must have missed it, thanks for your great work on these extensions.

Edit:
a new update has been released that fixed the jsx intellisense problem. I found out just after posting the previous comment.

I didn't know that a new version was available and indeed solves the intellisense issue. Thanks @luthv
