Use thin sidebar resize handle

[Cody Garver]

Since Marlin's left sidebar is resizable but doesn't use the big handle, BeatBox could do the same to maintain consistency and save a few px's.

Which CSS class?

[Victor Martinez (victored)]

I fixed this by adding a new style class: sidebar-pane-separator. This needs to be added to egtk as well.

It should look like:

.sidebar-pane-separator {
    -GtkPaned-handle-size : 1;
    border-width : 0;
    background-image : none;
    background-color : shade (@bg_color, 0.75);
}

In marlin we don't want all the pane and their separator from the column view to get the same style herited from the sidebar.
This why we target the specific class of the sidebar and it's pane separator like the following:

VarkaWidgetsHCollapsiblePaned {
    border-width: 0;
    -GtkPaned-handle-size: 1;
}

VarkaWidgetsHCollapsiblePaned.pane-separator,
VarkaWidgetsHCollapsiblePaned.pane-separator:prelight,
VarkaWidgetsHCollapsiblePaned.pane-separator:selected {
    background-image: -gtk-gradient (linear,
         left top,
         right top,
         from (shade (@bg_color, 1.30)),
         to (shade (@bg_color, 0.55)));
    background-color: alpha(#fff, 0.0);
}
