Recording Page Initial Commit

This is a VERY basic and alpha version of a page that provides
a list of recordings made when the Dial verb is used. There are
many untested cases still but this is a start.
Recording Playback Enabled

Playback is now possible using the Recorded Calls page.
Items of interest:
   - Added .htaccess for security
   - Added jPlayer to play recordings
Recording Page Initial Style

Make the Recorded Calls page a little less bland.
This may change further as I investigate the css for OpenVBX.
Recorded Calls Page Styling Update

The Recorded Calls page now looks a lot better. It uses standard
OpenVBX class names, with the option to override them in css using
custom class names.
Recorded Calls Page Heading Update

Fixed display of table header even when there was no recorded calls.
This happened when there were voicemails but no recorded calls.

The Recorded Calls page is ready for a base release.
 - Caching has been added.
