Added an opt-out option available from the button's dropdown

Refactored and fixed tools.image_resize_image() that converted to RGBA
after making thumbnails, resulting in bad looking picture in case the
source is in 'P' mode (indexed palette)

Fixes issue #1755 partially, when the new term
will be translated

[FIX] account: account_invoice's onchange_partner_id uses the first partner bank account if several are defined. Merge of #2280

Recently, the graph view was changed to prevent changing groupbys
for active custom filters.  Unfortunately, I did not take into account
the fact that pivot table can be drawn in part when expanding rows.

The "frozen" parameter was then undefined and caused display problems,
this patch should fix the issue.

[FIX] website_hr_recruitment: add param to force all countries else it use GeoIP, check that country returned by GeoIP have jobs availables else fallback on all countries

Fixing breadcrumb not being displayed after some action button (e.g. validate invoice, opw 612763)

remove module_boot() usage

The problem was that when the user manipulates the graph view (in pivot
table mode), the graph view resetted the group by facet in the search
view.  It was not a problem unless a custom filter with a groupby was
already there, in which case, the group bys were duplicated.

The search view is now smarter, it only resets the additional groupbys
(and col_groupbys).   Also, to prevent usability problems, the graph
view disable the '+/-' groupbys added by a custom filters.

Note that this fix is only temporary: a revamp of custom filters, facets,
search view is coming in the next months. (at least, that's the idea). Right
now, too much 'search logic' is in the graph view.

Another note: this fix is somewhat fragile: it makes some assumptions
about the search query (mainly that the custom filter is the first facet,
also, that no other filters add groupbys/col_groupbys)
