X-domain Basic Auth Support

Now supports Basic Auth via the built-in Moodle web service auth plugin.
* In order to accomodate capture of HTTP Authorization header in cases
where PHP cannot access headers natively, a mod rewrite .htaccess file
is included in the root folder of the endpoint. This will provide PHP
with access via the $_SERVER global for authentication when using Basic
Auth or Bookmarklet token-only requests.
(Now you can post statements using the TIN CAN statement generator!)
Minor bug fixes plus DB change

Minor changes with new version.
DB change includes allowing NULL for name field in agent table since
it's optional.
DB data storage change plus bug fix

Changed agent fields to store as json object vs. serialized array.
Upgrade will automatically convert all existing data to json.
Also, fixed query to match statement actor to previously stored actor
based on mbox or mbox_sha1sum.

Addressed completion logic changed in v.95.

Updated locallib.php to provide result completion of 'true' rather than
'completed' to conform with v.95 specifications.
Merge branch 'master' of https://github.com/jgsmitty/Experience-API-for-Moodle
Content end point logic change

A modification was made to the content enpoint of the API to eliminate
the 301 redirect method. It is presumed that it will be more efficient
as well as solve a discovered issue preventing the Articulate Mobile
Player from being able to access an embedded video when requested from
the content end point.
