Debug Start settings launch improvement

[jswigart]

I'd like to make a couple requests to the debug start UI/functionality to improve upon them.

The 'Debug Start' button currently does a standalone build for launching the clients. This can be a time consuming process, so I'd like to propose the following 2 minor improvements to this window.

1) Add a 'Debug Start Previous' to do the launch by itself, and skip the build. 2) Add a 'Debug Launch ScriptsOnly' so that it does the build, however it uses the BuildOptions.BuildScriptsOnly option, to skip the time consuming asset build process(provided you've done a full build at least once prior)

https://docs.unity3d.com/ScriptReference/BuildOptions.BuildScriptsOnly.html

Alternately(and I would prefer this frankly), make a 'Full Build' and 'Scripts Only Build' entirely separate buttons, and have the Debug start merely use whatever build was performed last.

Thanks for your feedback.

We've made some changes to the Bolt Debug Scenes window to accomplish some of these actions. It will be available on the next release.
