Feature - New API route - Recent QSO's

[patrickrb]

Resolves #3127

Added a new route to the API that returns the most recent QSO's.

There are 2 options you can pass in:

• detailed - defaults to false and returns all the columns if set to true in the request URL
• limit - defaults to 10 and limits the amount of QSO's returned to provided amount.
• limit throws an error if a user sets it higher than 100. - This can change, i figured it might be good to put a hard limit to prevent bad actors trying to slog the server down or something
• returns null if no qso's are found

Example routes: http://localhost/index.php/api/recent_qsos?limit=5&detailed=true http://localhost/index.php/api/recent_qsos?limit=1

Standard json return (not detailed)
