(Todo: work with the correct .rc file. Because tools are loaded only
  once. the defaulttoolsplugin.rc is not read and the toolbars are not
  populated. Don't know how to solve this right now.)
* Moved all generic tool interfaces and abstract classes to the core,
  where all tool plugins can use them.
* Made a tool registry/factory.
* Split the patterns/gradients/brush shapes docker into a fill and
  a shape docker.
* Detached the options docker by default because we've got too many dockers now.
* Moved the scoped lock helper class to tiles, which is the only place where
  it was actually used.
