PSS Updates #2
----
General Notes:
- Latest DB dump is in "db_backups", we truncated the orders/seat table to ensure accurate info for presentation. (You may have to truncate your DB before importing, didn't include drop statements). Make sure to import it otherwise you might see weirdness like tables claiming to have -2 packages available, or available tickets being at -288.

What is done:
- Update HD Tables sales model - Switched from seats to packages.
- Extract all pricing / configuration data into constants / config.
- Update prices for everything.
- Remove references to seats / tables in the sales flow.
- Create a hard limit of 30 (configurable in constants.php) for General Admission ticket sales.
- Create a time limit for HD Table orders (after 5 minutes order get's set as expired and seats related to the order are removed). The TTL is configurable in constants.php
- Database cleanup.
- Admin flow mode (see what is left).
- Any value worth configuring is moved out to constants.php
- Money is not longer manually formatted, instead we rely on money_format to do that for us.
