So many things can go wrong with this control in GTK. We have to
collapse the tree when updating the search string to avoid a crash when
referencing a child object but collapsing the tree will iterate over
elements and crash when we have deleted a symbol.
The temporary fix for this nonsense is to carefully order the calls.
We only need to collapse the search tree if we are not keeping our state
(in other words if we are fully re-building the tree)

This also picks up an additional line from 45aa514591 that keeps
CMakeModules/*.cmake. The rest of that commit does not merge cleanly.
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.
