Tomasz Wlostowski 379aa8f3b5 router: clearer distinction between LOGGER and DEBUG_DECORATOR classes.
The first one keeps a log of events (start routing, mouse motion, etc).
The second allows for adding temporary debug drawings and messages which are stored synchronously with the events in LOGGER.

The event stream together with the PCB design (now with UUIDs) can be used to deterministically replay routing bugs as the user sees them.

Jon Evans c0aa6965de Migrate PcbNew project settings to new framework
Various architecture upgrades to support this.
Creating a BOARD now requires a valid PROJECT, which caused
some (mostly transparent) changes to the Python API internals.

ADDED: Project local settings file
CHANGED: Board design settings are no longer stored in PCB file
CHANGED: Net classes are no longer stored in PCB file
CHANGED: Importing board settings now reads boards, not just projects

Jeff Young eb1ff80d57 SHAPE collision fixes.
1) An actual distance of 0 is still a collision, even if the allowed
distance is 0.
2) Be consitent about edges and interiors.  Everyone expect the edge
of a RECT to be part of the RECT; same with a CIRCLE.  SHAPE_POLY_SET
shouldn't be any different.  (And SHAPE_LINE_CHAIN was a split-
personality with the edge considered part of it for Collide() but not
for PointInside()).

Jeff Young d01b29ab37 Cleanup pad geometry handling.
There were a lot of plotters, exporters, etc. that were rolling their
own implementations.

This also introduces a lazily-built set of SHAPE objects for doing
collision detection and some forms of rendering (and later DRC).

This is the first step to allowing non-segments in the line chain.

Vertex() and Point() access routines and only leave the const versions.
Transformations are given for both points as well as the chain itself.

Seth Hillbrand 6625d0721e Implement Get/Set display options
The pointer passing for display options is deprecated.  This removes the
excess casting as the EDA_FRAME didn't need the base call with no value.
All requests for display options are now returned const and are updated
with a Set() routine after modification.

In Gerbview, this resolves an issue where the display options were not
stored because it was receiving the NULL from EDA_FRAME.
