	* app/toolsF.h: in other words: all tools

	Implemented the "reset tool options" feature.
	- All tools register with a title string and a reset function now.
	- The tool options' variables have two related <var>_d (default)
	  and <var>_w (widget) variables to restore the default values.

	"Standardized" the tool options UI:
	- Put the stuff info a frame to give a hint that the dialog's
	  contents will change.
	- table layout, sensitive setting, spacings, borders, ...

	As I had them all in my emacs simultaneously, I couldn't resist to
	standardize the tools' *.c files declaration parts ;) Ansi stuff.
