[IMP] crm: default filter is 'not dead' instead if 'unassigned' and displays an info message in the crm.stage form view. Dead leads should'nt be included in the default view since they can pollute the view over time. Instead, a filter for all leads (except the dead ones) is used by default. A small info message inform the user that the "dead" status is equivalent to setting probabilities to 0 and to fold the stage in kanban for a crm.stage.

[IMP] web: new pivot view, full rewrite of graph view

This commit is a split of the former graphview into a pivot view (the
tabular view) and graph view (the various charts).  The code was fully
rewritten.
* pivot view should be faster (better underlying data structure and
better algorithm)
* better integration with the web client (use of sidebar, of menu buttons,
bettor style)
* new feature: pivot view can be sorted
* new feature: pivot view cells can be clicked to open a list view with
the corresponding domain
* web_graph addon was removed, and the graph view code has been moved
to the addon web.
* the interaction with the searchbar was changed (no more column facet)
* better and simpler code for graph view
* mary corner cases in graph charts have been corrected (for ex, pie
chart with positive and negative numbers)
* graph/pivot correctly save their state when added to dashboard/saved
(state such as current measure, chart mode, column groupbys, ...)
