Add NULL printer to Force Printer Context menu

[Benjamin Kalish]

Sometimes it is desirable to prevent the printing of a single type print template. Currently you can use a print template containing nothing but an HTML comment to approximate this, but receipt printers will still advance the paper a small amount. The addition of a NULL option to the Force Printer Context Menu in the print template editor would allow folks to completely suppress the printing of that template.

Context:
My library requires Hold Slips to be printed, but hasn't required Transit Slips in some time and recently did away with Hold Transit Slips as well.

+1 to this. And while reviewing, it occurred to me the Angular (Server) Print Template UI does not yet support applying a custom print context. Opened bug #1891923 to address that.

From the commit:

Adds support to the Angular server template admin page for forcing a print context for a given template.

Adds support to the Angular print service for looking up the context of a print template when specified by name.

Adds support to And and AngJS print settings interfaces for a "No-Print" context, which bypasses printing when used.

Adds a new workstation setting for the Booking Capture server print template context.

I have marked bug #1891923 as a duplicate.

Works great! I tested on several of the traditional templates and on a new angular template as well.

I ran into a merge conflict with 950.data.seed-values.sql while trying to sign off through git, so I'm signing off here:

Thanks, Terran. Rebased with sign-off added:

Will ping Galen on merging since it's a mix of wishlist and bugfix.
