* changed all the RotatePoint() functions in trigo.{h,cpp} to take a double as the
angle, which is still in tenths of degrees for now.
* EDA_TEXT::m_Orient is now double, still in tenths of degrees (for a short while),
but the double means parsing files and saving them use a different format string.

* DRAWSEGMENT::GetStart() and GetEnd() do not operate for S_ARC like they used to.
They are now simply accessors for m_Start and m_End. Use DRAWSEGMENT::GetArcStart()
and GetArcEnd() and GetCenter() for arcs. specctra_export.cpp was the only
source file dependent on the old behavior.
* DIMENSION::m_Text is now contained, not dynamically allocated.
* more kicad_plugin work.
In common.cpp GetTimeStamp is renamed GetNewTimeStamp (a better name).
Pcbnew: prepare work to calculate connections between pads that inteserct and therefore can be connected without any track (composite pads).
the GetPosition() and SetPosition() changes. It also starts towards making m_Orientation
and m_Thickness fields private with accessors, but does not complete this latter goal.
* All header files used to create the PCB common library now compile as
stand alone code. This prevents the need to define them in a specific
order to make source code compile properly. It should also now be
possible to relocate the source code to build the common PCB library
to a separate folder.
* Move various locate functions into the appropriate board item object.
* Unified best zoom for all frames derived from PCB_BASE_FRAME.
* Remove track.cpp as it is no longer needed.
* Dead code removal.
* Remove scary frame window pointer member from board item objects.
* Add draw bounding box to gerber draw item for debugging purposes.
* Move schematic wire and bus break code into schematic screen object.
* Move schematic test for dangling ends into schematic screen object.
* Remove left over debugging output in schematic screen object.
* Remove unused file eeschema/cleanup.cpp.
* Fix bug in schematic line object hit test algorithm.
* Fix a string concatenation compile error added in r2752.
* Rename class WinEDA_BasicFrame to EDA_BASE_FRAME.
* Rename class WinEDA_DrawFrame to EDA_DRAW_FRAME.
* Rename class WinEDA_DrawPanel to EDA_DRAW_PANEL.
