better handling of libraries paths (removed g_RealLibraryBuffer that had no sense with the new code), mainly in Eeschema
TODO: better handling of user lib paths (more than one path)

Add helpers for inserting paths to and removing paths from search list.
Moved user defined path before default library paths in search list.
Renamed m_Draw_Auxiliary_Axis to DrawAuxiliaryAxis.
Changed parameter to fix wxDC set mode from FALSE to GR_COPY.
Minor wxDC zoom improvements.

Added application method to fix searching for user libraries.
Fixed documentation search path bug.
Moved auto pan setting from draw frame to draw panel were it is defined.
Some minor device context drawing changes.

Added template subdirectory to library search path list.
Removed PARAM_CFG_BASE empty destructor to prevent GCC warning.
Set timeout to 0 on DisplayInfo call to prevent debug assertion in eeschema/files-io.cpp.
Declare PARAM_CFG_ARRAY for future project file object implementation.
Removed unnecessary COMMON_GLOBL definition in gr_basic.h and param_config.h.

Global variable unobfuscation, new library path search, and lots of other changes.  See CHANGELOG.txt.

Dialog track options redesigned with wxFormBuilder Alt via drill renamed Specific via drill. Added tips in dialog.

Mandatory in Pcbnew to handle without error metric grid used now for some footprints (BGA, connectors)
Not fully tested

Integrate wxFileHistory, add missing header files to fix Linux build, initial search path work, and general housekeeping.
