- refactored the imports in the Plugins, moved almost all imports in the AppTool file

- fixed a number of issues, mostly leftovers from moving the UI of a Plugin in its own class
- fixed some bugs in the Punch Gerber plugin
- fixed some bugs where the 'pool' parameter was not passed when creating shapes collections (in 3D graphic mode); I wonder how it worked until now
- added a new feature in the Isolation Plugin: now for all the isolation Geometry objects this plugin can do a supplementary simplification of the geometry using the tolerance parameter defined in the General Parameters. This should lead to a reduced number of tool lifts when doing corners
