php-collection: New graph toolbox

This patch creates a new toolbox which can be show on a per-graph base
by clicking on a graph.

This box allows changing the displayed period of the selected graph
as well as toggle the logarithmic scale and legend details flags.

The graph reordering, refresh and delete tools have been moved from
right graph edge to this new toolbox.
