Create JS-only version

[tinok]

Ideally, kobomaps should use only JavaScript and HTML, without any PHP.

The various maps could then be hosted on S3 and get updated whenever there is a new commit to master.

PHP was used initially to allow embedding the map in a Drupal environment, but that is not the best solution long-term.

@nstraub I have created two maps that don't require PHP in the peacebuildingdata branch. This required making two small changes in the data_visualize.js file. The index.html file pulls together mapheader.php, mapcontent.php, config.php, and index.php.

It would be nicer to continue using templates for mapcontent and mapheader so updating each map isn't a hassle in the future.

@tinok the rewrite branch doesn't depend on PHP at all, maybe after the festivities are over we could discuss merging it into master or peacebuildingdata

I saw your recent changes @nstraub ... should we consider merging it into the main branches?
