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.

   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.
