Title: Live add remove + other changes

- removed `xdata.tween`, all tweens are appended on-the-fly, since they are hot
- implemented priority order in modifiers and painters, mostly to keep required tweens order
- now only `return false` means modifier not passed, omitting return statement is qualified as 'pass'
- it is allowed to add elements on the fly. removing and disabling is also supported
- it is allowed to add modifiers on the fly
- added `anm.` prefix to animatron files
