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.

eeschema: fixed: void history file list in menu

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.

pcbnew: added 5 metric grids and fixed a very minor bug when creating drill map.

Changed 3D module author after mail contact. Cleanup of function implementions. WinEDA_TextFrame color change (text black, background, white)

gr_basic.cpp now clips filled polygons,using the Sutherland and Hodgman algo to clip the poly against a rectangle
Filled polygons are now correctly displayed under Linux(i hope)
