Pcbnew: Code cleaning and bug fix in autoplace functions
Dialog exchange footprints has now a separate button to update the .cmp file, only on request.
File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
* Improve MSG_PANEL_ITEM to handle message panel information.
* Create containers for passing message panel items between objects and
the message panel.
* Rename EDA_ITEM::DisplayInfo to EDA_ITEM::GetMsgPanelInfo.
* Remove all direct manipulation of EDA_DRAW_FRAME from all objects derived
from EDA_ITEM.
* BLOCK_SELECTOR class is not longer derived from EDA_ITEM.
* Encapsulate BLOCK_SELECTOR class member variables and add access methods.
* Move HandleBlockBegin() function from block_commande.cpp to drawframe.cpp.
* Remove virtual methods from top level derived objects per future
coding policy change.
* Remove Doxygen copydoc statement from objects derived from EDA_ITEM
since the comments are automatically copied to the derived object.
* Removed copy and pasted Doxygen comments from objects derived from
EDA_ITEM.
* Remove unnecessary copy constructors from schematic and component
library objects.
* Add comment to class definitions where the default copy constructor
generated by the compiler was adequate.
* Add assignment operator to EDA_ITEM, SCH_ITEM, and all schematic
objects where the default assignment operator generated by the
compiler would not be adequate.
* Create library collector class.
* Add clarification menu to library editor when multiple items are found
at the current position.
* Add get clarification menu text to all objects derived from LIB_ITEM.
* Add get menu bitmap for all objects derived from LIB_ITEM.
* Improve LIB_PIN bounding box calculation.
* Rename LIB_ITEM::DoGenCopy to doClone to match behavior defined in base
class EDA_ITEM.
* Minor class renaming for improved code consistency.
* Added less than operator to EDA_ITEM.
* 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.
* All library component object editing is now performed with the ojbect
except LIB_PIN (coming soon).
* Added TRANFORM class to handle coordinate transforms.
* Remove old transform matrix functions.
* More file renaming to align them with the other component library
object file names.
* Fix hot key bugs in library editor to disable edit keys while an item
is being edited.
* Fixed bug when cancelling rotation of text and field objects while
being moved.
* Break classes_body_item.cpp(.h) into more reasonable size bites.
* Rename classes_body_item.cpp(.h) to lib_draw_item.cpp(.h)
* Fix some unsatisfied header file dependencies.
* Add stubs to component library draw item base classe to handle editing
internally.
* Lots of code cleaning.
