Update TODO.txt to reflect completed FP_LIB_TABLE items.

b) in the uri column give a small button popup a window(dialog?) which lets user choose a file or directory local to his system by pointing at it.

c) Active library table load and save functions.  There are two tables active at any time, but

they look like one table.  Identify a place to keep the access mechanism (pointer).  Modify

the project specific portion of this RAM table when the board changes.

a) develop a syntax for nickname:footprint combo, i.e. bring to life class FPID

 with development and testing of parsing and formatting.

b) modify cvpcb to handle the nickname:footprint, i.e. textual form of FPID.

This means having a wider textfield for the FPID than was allocated for the footprint name alone.

Needed is the ability to pick a footprint from any active library.

c) modify the netlist format to handle nickname:footprint, save and load.

The nickname needs to be optional.  I would say allowed in the grammar in the

footprint position are:

    footprint | (fp_id FPID)

or just

    FPID   # if it can be parsed when nickname is missing.

d) write functions to lookup a footprint from

 i) FPID

 ii) footprint alone since most old netlists don't have nicknames in them.

e) Replace MODULE::m_LibRef which is a wxString with FPID.  FPID supports

   the footprint name only which is backwards compatible with the current

   design.

f) On the first time an empty global footprint table is encountered, add

   standard KiCad and user libraries not located in the project directory

   or any of it's sub-directories to the global footprint library table.

g) When a project is opened and the project footprint library table is

   empty, add any user library that is located in the project path or any

   of it's sub-directories to the project footprint library table.

h) When populating the footprint library tables, use the library  file name

   without the extension as the FPID nickname.  When duplicate names exist,

   append an incremental integer to the nickname so that the second logic

   libraries FPID nickname becomes logic1.  Assign FPID library nicknames

   to each MODULE based on the legacy library search order when loading an

   existing board that does not have fully defined MODULE FPIDs.

i) Add check for KISYSMOD environment variable, on Pcbnew and CvPcb start up

   and set it to the known directory of the default KiCad footprint libraries.

   The code should look something like:

{

    const char* envar;

    envar = getenv( "KISYSMOD" );

    if( !envar )

    {

        envvar = knownDirOfSysMods;

        setenv( "KISYSMOD", envar );

    }

}

These i) and ii) merge into one if footprint alone is a valid FPID.

Incorporate any environment variable in the the uri expansion using:

const wxString FP_LIB_TABLE::ExpandSubtitutions( const wxString aString )
