David Markowitz 7338319fac feat: debugger additions 
Add type field for links in flash
Add warning level for dangerous buttons
fix uninitialzied memory with jetpack variable
remove a bunch of duplicated position push code

tested that the ui is still functional and components with multiple physics components have all their details visible.
tested that jetpack is initialized now
