Footprint library table work, minor fixes, and code cleaning.

* Fix a bug when full file name and path are passed to FOOTPRINT_INFO::
  ReadFootprintFiles() which I created in bug fix lp:593989.
* Fix a wxString debug assertion in EDA_APP::InitEDA_Appl() when the KICAD
  environment variable is defined as an empty string.
* Add error dialog when libraries cannot be found in system search path
  when loading footprint using the select footprint dialog.
* Add footprint library name column to the EDA_LIST_DIALOG when selecting
  footprints from the list.
* Allow reading all columns from the selected row in EDA_LIST_DIALOG.
* Remove redundant sort from EDA_LIST_DIALOG constructor
* Add library name member variable and accessors to FOOTPRINT_INFO.
* Make headers translatable for Eeschema select component from list dialog.
* Add some helper methods to FPID for identifying the FPID type and validity.
* Remove a bunch of trailing whitespace and add missing license comments.
