Implement ZWELCOME Routine

[nikitaeverywhere]

There is such thing as ZWELCOME routine in Caché. It allows to print arbitrary text in Caché terminal upon its start.

Example (must be compiled in %SYS namespace):

ZWELCOME() PUBLIC ;
    ; Example
    Write !
    
    Set ME = ##class(%SYS.ProcessQuery).%OpenId($JOB)
    
    Write "Now: ", $ZDATETIME($HOROLOG, 3, 1), !
    Write "Pid/JobNo: ", ME.Pid, "/", ME.JobNumber, !
    Write "Priority: ", ME.Priority, !
    
    Quit

It would be nice to have this in WebTerminal.

Does anyone use this thing?
