fixed bug where quotes were not added to the dir name when you click
the dir button.

fixed inheritance problem with qt widgets that prevented OneFinger to
work on mandrake.

Added toolbar button to remove all narrowing file->program at once.

code cleanup. Someuseless code has been removed. 

Added debug messages useful in bug reports.

The items in the arguments panel now have two buttons (enter directory
and suggest), like the file panel.

Now, when no program has been entered, the arguments list shows a list
of arguments used with ANY program. Useful to have a list of file from
any location.

Now using bash itself to tokenize the string. This solves many parsing
bugs, some of which can cause loss of data.

Improved tooltips.

Narrowing file->program.  When the mouse goes _over_ a file, highlight
the program that can manage it? This is not possible because the
program may not be visible in the list. Could we use a tooltip on the
file, which reminds you of the typical viewers? yes, but then the user
would have to select the viewer himself, by scanning the program
list. This is not ideal. The right solution is to add a TOGGLEbutton
besides each file (maybe a glasses icon) which, when clicked,
automatically hides the unreasonable programs: it only leaves those
programs that have registered themselves as viewers of that mimetype,
OR that have have previously been used with that mimetype nonetheless
(this way OneFinger _learns_ what program can manage a given file).
-------- Note: we cannot simply only add ONE togglebutton, besides the
program panel, that narrows the programs to only those ones that can
manage the SELECTED FILE. Because you'd have to select the file
first. -------- The narrowing icon is a light bulb, standing for
"suggest".



Some programs like cvs force you to be in a precise path when
launching the program. How to specify the pwd? We need a button to set
the current dir. We can use the dir icon itself!
