webmaster Queue Fix

The issue stemmed from a lack of error handling for empty header information from additional info supplied from user sections. That has now been fixed with #140

Additional info supplied by user structure:

=== Additional information supplied by user ===

Subject:  Subject Line Here
From:  "From_Name" <email@aol.com>
Cc:  "epicsite@ecn.purdue.edu" <epicsite@ecn.purdue.edu>,
            "CC Name One" <ccone@purdue.edu>,
            "CC Name Two" <cctwo@purdue.edu>,
            "CC Name Three" <ccthree@aol.com>

===============================================

The structure consists of a beginning delimiter, a newline indicating header information, header information, a new line indicating the end of the header information and the beginning of the content, two new lines and the ending delimiter. However, the below queue resulted in an error during the date sort within the api:

=== Additional information supplied by user ===


content


===============================================

The problem with the section above (taken from webmaster 137 in the live queue) was with the handling of the header information. The api does not expect a fixed number of lines within the header, meaning that 0 lines of header information can be included within the reply-from-user section and still result in a successful parse for the rest of the section. However, a line indicating the date of the section must be provided in the header so that the script can sort the section by date, something that was not checked.
In order to successfully parse correctly, the api now looks for a date in the header info and returns a parse_error if none is found.

Two things are wrong with this item:

1. There is no initial message, which is currently not expected behavior and it throws an error when trying to parse content that doesn't exist. Fix: implement a check before trying to parse content to ensure there is an initial message
2. The first line of the header information is malformed and will likely cause an error if this item had an initial message. Fix: check for malformed header information.

From: abuganza is a malformed line in which a header line starting with From: needs to contain an email address with the @ symbol. This line doesn't contan a full emai, resulting in an error when attempting to parse. Fix: Check for malformed header info.

same problem as webmaster Queue fix from above

Parsing issues should be moved from custom logic to a proper parsing grammar.

Not sure if this can be closed. Asked @benne238 in Slack for an update.
