new version of the script with many changes
-dryed the script (I'm not a programmer...be patient)
-now changes also contrast settings
-put a restore to default (mine one, the better I found up to now are gamma 2.5, contrast min-max 0-100)
-put a very simple help
-now the menu shows settings directly
many many thanks to rkomar's sh_ivtool and jtt(Jens)'s vip programs
