Noise brush - Greatly improved performance on large layouts

Profiles core - Pass real delta time brushes/effects
Profiles core - Allow main segment to be disabled on layers
General module - Removed test data model
General module - Removed expensive open window scan, was fun to try :P
Profile editor - Refactored segments
Profile editor - Updated segment visuals to scale well when really narrow
