Add simulation start and pause messages to unified log; auto reset log files

[jdalbey]

When "Start" is clicked in the Sim Mgr add an entry to the unified log similar to this:

Simulation started at 03 Mar 2020 09:02AM with incidents 181, 182, 185.

When "Pause" is clicked, add an entry

Simulation paused at 35:05.

When the Sim Mgr starts the default behavior should be to reset the unified log files. Add a checkbox to the UI if the user wants to retain the existing files.

Test case 1

Clear CADcomments.log. Start Server. Start Sim Mgr with full script. Click "Start". CADcomments.log should contain

CAD log, Simulation Started,  loaded incidents 100 187 188 189 190 191

Click "Pause". CADcomments.log should contain

CAD log, Simulation Started,  loaded incidents 100 187 188 189 190 191 
CAD log, Simulation Paused.

Click "Resume". CADcomments.log should contain

CAD log, Simulation Started,  loaded incidents 100 187 188 189 190 191 
CAD log, Simulation Paused.
CAD log, Simulation Started,  loaded incidents 100 187 188 189 190 191

Test case 2

Clear CADcomments.log. Start Server. Start Sim Mgr with full script. Click "Start". CADcomments.log should contain

CAD log, Simulation Started,  loaded incidents 100 187 188 189 190 191

Start CAD Client. Login as user "A". Open incident 187. Enter comment "Hello world". Click "Exit/Send". CADcomments.log should contain

CAD log, Simulation Started,  loaded incidents 100 187 188 189 190 191 
CAD log, Incident #187, A: HELLO WORLD

Click "Pause". CADcomments.log should contain

CAD log, Simulation Started,  loaded incidents 100 187 188 189 190 191 
CAD log, Incident #187, A: HELLO WORLD
CAD log, Simulation Paused.

Completed the enhancement that updates the unified log.  Committed in r524.

Moving "auto reset" to a separate ticket.

[jdalbey]

Add the date and time to the content of the "Simulation Started message". Use

SimpleDateFormat("d MMM yyyy HH:mm:ss")

Fixed in r529. Sample output in CADcomments.log:

CAD log, Simulation Started at 19 Nov 2019 20:33:10 with incidents 100 187 188 189 190 191
