Various improvements

1) Support connecting user action signals after the default signal handler: 
maybe <action signalafter="button-press-event">echo 
button-press_event</action>. They're all connected in widget_connect_signals.

2) A right-click menu.

3) <table> column sorting: a sorting function needs to be written and activated 
when a header is clicked.

4) <tree> rendering similar to <table> i.e. after shown: no idea about this.

5) Supporting <item stock=gtk-open>coloumn1|coloumn2</item> from an input file: 
see fill_tree_view_by_command.

6) (Moved to the scales/sliders feature request).

7) <menu> submenus.

7 is started but it'll be a while as it's complicated.

7 is done.

5) I came across an example 09.03-tree_icon_columns that supports <input 
stock_column="0"> which accepts a stock icon as the first column 
(icon_column="0" also works). So you can use this:

function list() {
    ifs="$IFS"
    IFS=
    echo $(<list)
    IFS="$ifs"
}; export -f list

in combination with <input stock_column="0">list</input> or <input 
icon_column="0">list</input>

I'm working in the lexer/parser and I've noticed that <input file> does 
actually support tag attributes so <input file stock_column="0"> is possible.

5 is fixed. Oddly it was all in place to work but simple changes to complete it 
weren't done, almost as though development had stopped and it remained 
unfinished.

3 is done in r400 with an optional natural sort too.

The unnecessary exporting of variables which contain large amounts of data 
should be addressed, for example an edit widget which contains a README that 
doesn't require exporting but it gets exported because its variable name has 
been declared -- this could possibly be dealt with by using <variable 
export="false">VARIABLE</variable>.

Loading a null pixmap i.e. <input file>""</input> causes a segfault which is 
not the best way to tell the application developer that a valid file is 
mandatory. Actually I don't like the fact that it's mandatory and in the wiki 
it's the sole reason why there exists a mandatory column, so get rid of this 
requirement.

Inputting nothing into the edit widget causes a gtk+ critical message although 
it doesn't cause any problems. This has been like this since at least 0.7.20 
and it should be fixed consistent with other comparable widgets.
