flSynclient: fltk frontend to the command line tool synclient

Needs:
 - a touchpad supported by the synaptics driver, 
 - the driver itself installed,
 - synclient (command line tool for synaptics driver), 
 - SHMConfig "on"

Your XF86Config/xorg.conf should contains something like:
------------------------------------------------------------------
Section "InputDevice"
        Identifier      "touchpad"
        Driver          "synaptics"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "auto-dev"
        Option          "SHMConfig"             "on"
EndSection
...
Section "ServerLayout"
	...
        InputDevice     "touchpad" "AlwaysCore"
EndSection
------------------------------------------------------------------

flSynclient saves his setting in ~/.flSynclient

Saved settings can be restored every startup using the command:
    flSynclient -s 

Tested settings can be definitely saved in XF86Config/xorg.conf
adding a option line for every option in ~/.flSynaptics:

------------------------------------------------------------------
Section "InputDevice" 
        Identifier      "touchpad"
	.
	.
	Option "Optionname" "OptionValue"
	Option "Optionname" "Optionvalue"
	.
	.
	.
EndSection
 ------------------------------------------------------------------
   
INSTALL:
 - make
 - make install
 
NOTE:
 - after the "make" you can test the program immediatly with:
   ./flSynclient
 - the make install copies the binary in /usr/local/bin
   and the pixmaps un /usr/share/pixmaps , for different
   location you can copy the three files manually
   
TODO
 - man page
 - set char dimension and colors on start
 - internationalization (GNU gettext or POSIX catget)
