kicad-install.sh: fix bad url for legacy libraries. Add the same script hich does not need a bazaar account to download Kicad (using https instead of ssh to create branches)

kicad-install.sh and library-repos-install.sh utilize /etc/profile.d/kicad.sh for setting environment variables globally

*) Add scripts/library-repos-install.sh for downloading *.pretty libraries and possibly using them.
*) Remove template/fp-* files, they are now at https://github.com/KiCad/kicad-library/template/*
   so they can be maintained by the library team.  However note that it is possible to break
   kicad-install.sh with uncoordinated changes to that github repo.

It is best to delete your ~/kicad_sources/kicad-lib.bzr directory before running kicad-install.sh
at this or any newer version relative to an older library repo.

add libglew-dev prerequisite for debian systems, it pulls in libgl1-mesa-dev and libglu1-mesa-dev on its own

Add support for building *.deb file using CPack, install ~/fp-lib-table either from kicad-install.sh or from make install_user_configuration_files

Write parser and formatter for options.  Write dialog verification used before saving
FP_LIB_TABLEs, triggered from OK button in table editor.
Switch PROPERTY's value column to std::string from wxString.
Add event handler to fp lib table dialog for upcoming options dialog.

Enhance IO_MGR::GuessPluginTypeFromLibPath() to support the GITHUB plugin.
Build boost with -fPIC on Linux unconditionally, in preparation for
DLL/DSO build of kicad.
Add python script to test back to back reads of GITHUB plugin.

Significantly enhance the bom_csv_grouped_by_value.py BOM generator.
IMO it at this moment, the best BOM production tool for KiCad.

*) add hotkey for setting the grid origin as 'S', in board editor, module editor.
*) re-position the function interface for cursor movement from BASE_SCREEN into
   class EDA_DRAW_FRAME.  This is a prelude to getting rid of BASE_SCREEN or
   splitting it up.

Add script to make a footprint library table from the KiCad Bazaar library repository, either in s-expr or CSV format.  Add also the generation of such tables as of today.
