Patch to add simple batch replacement functionality

This patch add an item to the samples tree pop-up menu that let you select a
folder with wav files that will be imported and replace samples with the same
name already in the gig file.

Seems Andreas is busy. I review the patch now.

Ok, I just commited it to CVS. I extended your patch a bit:

* the postfix for the filename (was hardcoded ".wav") is now user adjustable 
by an entry box in the directory select dialog

* added a detailed description about this function to the directory select 
dialog, because I think the regular user would be absolutely clueless what to 
do do with this function (note the ugly line wrap behavior of the description 
label: it doesn't adjust correctly to the correct dialog size yet, which is a 
gtkmm issue I haven't found a workaround yet - see also the commented FIXME 
code which I tried to fix this issue)

* using G_DIR_SEPARATOR_S instead of "/" to keep the code portable

* showing an error dialog at the end with all samples that failed to replace

Thanks Anders!

Trial to circumvent the line wrap bug of Gtk::Label

This is BTW the last thing I tried yesterday to circumvent the mentioned bug of
Gtk::Label regarding line wrapping of long text. I tried to call
Gtk::Label::set_size_request() each time the dialog resizes, because that call
was recommended in the gtkmm API docs to circumvent the problem, but
unfortunately it will only set the minimum widget size of the label. That is,
the text will correctly adjust itself to the parent's container size, but you
won't be a able to shrink the dialog anymore... you can only enlarge it more
and more. :)

Should we fix that previously mentioned Gtk::Label line wrapping issue in the 
dialog? Otherwise I suggest to close this report.

I found a label implementation that seems to line wrap correctly in "libview",
http://view.sourceforge.net/, and copied it to gigedit.

Closing this report now, due to the current huge list.
