Added time slot availability checking at appointment save time to avoid double booking errors.
In our previous commit of "Payment Popup", we had made modifications to insert the COPAYs to ar_activity table instead of billing. Also we have made a script to transfer the existing COPAYs from billing table to ar_activity table. In the function ar_get_invoice_summary, we are fetching the COPAYs from the billing table. We have now added an extra modification to fetch the COPAYs from ar_activity table also.

Added a Provider entry to patient demographics.

 -Since the current provider entry in demographics was
  being used both as referring provider and main
  provider in the codebase, did the following:
  -Made the current providerID entry only for the main
   provider.
  -Created a new ref_providerID entry for referring provider
  -For upgraders, copied the providerID info to the
   ref_providerID field to ensure previous fx is not broken.
  -In codebase, elements that were using providerID to collect
   the referring provider now map to ref_providerID.
