The 8.3 update broke the designer debugging config I had for 8.1

These are the VM options. Which the /main gives a 404 error

-Djavaws.sr.gateway.addr.0=localhost:8088/main  
-Djavaws.sr.main=com.inductiveautomation.ignition.designer.DesignerStartupHook  
-Djavaws.ignition.debug=true  
-Dautologin.username=\*\*\*\*\*\*  
-Dautologin.password=\*\*\*\*\*\*  
-Dproject.name=TheProject  
-Djavaws.sr.runtimeOverride=true  
-Dignition.version=dev

Removing that and just having “-Djavaws.sr.gateway.addr.0=localhost:8088” allows the designer to start, but it gets disconnected from the designer before logging in

We renamed some of the system properties; try swapping `javaws.sr` for `ignition`, as in (note: I don't recommend setting all these properties; this is just the example debug config I'm currently using out of the IDE):

```python
-ea
@/Users/pgriffith/Projects/ignition/.run/client-designer-args.txt
-Dignition.version=dev
-Dsun.java2d.d3d=false
-Dignition.client.debug=true
-Dignition.client.logLevel=INFO
-Dsun.awt.nopixfmt=true
-Xmx2G
-DlibPath=/Users/pgriffith/Projects/ignition/IDE-Launchers/gateway-launcher/src/main/home/user-lib/pylib
-Dignition.gateway.addr.0=localhost:8088
-Dignition.gateway.addr.1=localhost:9088
-Dawt.useSystemAAFontSettings=on
-Dswing.aatext=true

```

Thanks! That worked
