Scripts to new look 1

[fho4abcd]

Introduction of the new look gave also rise to some additional changes. It includes conversion of old style buttons + div-helper. Additionally:

• pft.php: echo html code is written as html code. The layout of the various sections is improved too. Using a saved search works now as expected.
• inc_back.php: acts now also on "encabezado" and accept values of "backtourl" with some attributes already added (example: $backtoscript="myback.php?opcion=new";)
• inc_cancel.php is new and shows a cancel button. It acts on $backtocancelscript

Fred, I couldn't evaluate it calmly, but toogleLayer has stopped working. I don't know if you will keep on messing with this file, but I have some ideas for it.
