Contributing translations directly from github

I learned this when working with the contribution of the Croatian language.

Technically, any non-code contribution can be made this way, so maybe there's a better place for this.

I was not clear when I first read this sentence until I actually click on the [+] button. So it may be clearer to mention that clicking on the [+] button will bring you to a new page with a text field for your new filename. You can create subfolder in the same text field.

[RaymondLim]

Maybe you should describe how to get the English copy to the editing page so that translators know where to get the source code.

Done.

@RaymondLim Ready for another review. I took your advice and walked through all cases, so I added a lot more detail.

[RaymondLim]

How about adding the following as step 4.

Add this comment /* Last translated for SHA_of_root_strings.js */ at the end of your strings.js and replace SHA_of_root_strings.js with the actual SHA. You can copy the actual SHA in this [history page](https://github.com/adobe/brackets/commits/master/src/nls/root/strings.js) by hovering on the one you used for this translation and click on Copy SHA button.

[redmunds]

Done, but I added as Step 3 since this is where file is edited.

[RaymondLim]

Looks good, but I would like to enforce web interface users to record SHA as well.

Ready for another review.
