* Add code to test if any of the components in the schematic cache have been changed
in the component libraries.
* Prompt user to accept or reject components when changes are found.
* If the user chooses to use the components in the cache, create a new library with the old
components and add it to the beginning of the component library list so the schematic will
not be changed.
* Create dialogs to handle user feedback and status.
* Use "Close" in the file menu of every main frame window instead of the
mismatch of the terms "Close", "Exit", and "Quit".
* Change the terminology in the Pcbnew graphic text edit dialog to match the
module text edit dialog.
* Improve the layout of the Pcbnew graphic text dialog.
* Fix some wxPrintf parameter type assertions for 64 bit time_t.
* Fix all (at least I think I got all of them) duplicate menu accelerator
characters.
Now these parameters are stored in user config, not project config ( they are not really related to a given project, they are just a setup during an edition),
and the schematic editor and the component editor have now separate parameters, because they are separate editors with different constraints.
component editor: repeat pin enhancement (from and idea of Edward Johns)
Previously, only the lib named "power" was used (and therefore power parts defined in other libs not shown).
Now, all power parts can be loaded from any library.
Also, when loading power parts from the chose component dialog or the lib viewer, libs and parts are filtered: only power parts and libs containing power parts are listed.
Hotkeys: move a few global strings in the files where ther are actually used (and make them local.) and code cleaning.
Fix a few other minor issues.
Fix some issues in filling zones normals.
Fix an issue with some models that have materials but didn't defined the diffuse color.
Workaround for Bug #1443431.
Implement some missing "code logic" for pervertexperface normals.
Remove some not used functions.
Calculate normals using double type.
* The SCH_COLLECTOR m_foundItems was being obsoleted after a pin name search.
If a library edit changed the found pin name, the cache still held the now
missing library pin and would segfault on next search due to the cache being
out of date.
* Remove redundant definition of KICAD_DATA_PATH since DEFAULT_INSTALL_PATH
was already defined.
* Use DEFAULT_INSTALL_PATH as the substitution for the default environment
variable paths.
* Add option to define DEFAULT_INSTALL_PATH during CMake configuration with
fall back to CMAKE_INSTALL_PREFIX if not not defined.
* Developer note: this change is primarily for package builders where
CMAKE_INSTALL_PATH is the path where the package builder temporarily
installs the build output before creating the package. When building
packages, DEFAULT_INSTALL_PATH should be set to the path where the
package will be installed by default.
