Use full REST API URL (with index.php)

"Nice" REST API URLs are configured in MantisBT api/rest/.htaccess
file. If the Apache setup does not allow overrides, then the web server
will return 404 errors because mod_rewrite is not enabled.

To avoid issues on sites where URL rewriting does not work, we use the
full URL with index.php for AJAX requests, i.e.

    http://example.com/mantis/api/rest/index.php/plugins/Snippets/...

instead of the "nice" URL

    http://example.com/mantis/api/rest/plugins/Snippets/...

Fixes #31
