Merge branch 'develop' of https://github.com/CORE-POS/IS4C into devel
Refactor: remove references to mysql_connect.php and trans_connect.php
Use FannieDB instead of uniformity. Also removed references to
select_dlog.php and replaced with DTransactionsModel::selectDlog.
The older version requires a database connection and assumes a
global variable $dbc. The model version is strictly self-contained
and does all the date calculations in PHP
Remove "global $dbc" usage. Functions requiring a connection
should request one via FannieDB to ensure the connection is
pointed at the expected database.
Added "Rings" column. Only differs from quantity on by-weight items

syntax that was throwing warnings and notices
