Trigger ZoneMinder event on card insertion/removal

[adnbr]

ZoneMinder includes the option for external triggers - a future enhancement could be to grab a frame or short clip at the start and end of each machine session.

Can be used to keep track of machine usage and evaluate state of machine when it is left. Would require an extra column in the machine table to track the ZM monitor that should be triggered.

There is the ability to overlay custom text, which could be the username or carduid, and the machinename currently in use.

Adding another column in the machine table is easy enough to do. Looking at the documentation for ZoneMinder this looks pretty easy to implement - a TCP connection to the ZM server and then sending a string.

Would it be worth considering this now (whilst we're still building the core functionality) or is this more of a future thing?

It should be easy to add at a later date, no rush for now.
