Check for Net_Growl
Start using UnknownElement to wrap all tasks
Initial implementation; wrapping all elements in UnknownElement, add implicit target to new projects
Move implicit target to parsing context, execute it after parsing, ignore in logs (import still broken)
Parse imported file, move current targets to context, reset stack during imports
Add/replace targets, use reference for current targets array
Tasks are now wrapped, use the proxy
Explicitly call init()
Tasks are wrapped in UnknownElement
