Start work on HtmlLPO

The current LPO is based on openrpt. This produces a messy and
bulky PDF file. The purpose of this branch is to come up with
a simple HTML LPO file that will be exported to a Clean PDF
file, which can then be emailed.

Abandoning erp_mailer, Back to queue_server

The HTML to PDF idea is on a shelf for now. I will polish up
the queue server daemon and will revisit the HTML lpo later,
maybe with a PHP stores application.
