LIB_ID was changing the symbol name due to the parser dropping everything
past the first '/' character which is interpreted by LIB_ID as the item
version. Add flag to ignore this in LIB_ID::SetLibItemName() and add a
new ctor so the library nickname, item name, and revision can be set as
required to prevent the standard LIB_ID parsing.
Fix a few places where PART_LIBS functions FindLibraryAlias() and
FindLibPar() were translating wxString symbol names to LIB_IDs where the
LIB_ID parser was truncating the symbol name.
Rename FPID to LIB_ID as is now used as a generic library identifier and
is no longer specific to footprints.
Remove all mention of footprint from the new LIB_ID doxygen comments and
code.
Rename files fpid.h and fpid.cpp to lib_id.h and lib_id.cpp.
Rename fp_lib_table.keywords file to lib_table.keywords and adjust CMake
build dependencies accordingly.
Update all source files effected by the code and file name changes.
Update .gitignore for file name changes.
