Make report_webkit thread safe by removing parser_instance attribute, as a WebkitParser instance can be shared by multiple thread and thus we don't want a thread to erase parser_instance of anorther thread.

[IMP] work on inline search view in web client

incomplete work.  So far, the search view widget has been split in
two widgets: SearchView and SearchViewDrawer.  The SearchViewDrawer
has been inserted inline, and some preliminary work has been done
to improve the layout.
[FIX] add support for default filters in search view

support for default filters was broken in the previous commit,
now it works again.
[IMP] lots of layout work for inline search view (addon web)

mainly to correctly style the custom filters list.
[IMP] hide drawer when switching views (addon web)

the drawer wasn't closed when switching views, which might be a
problem when the user switches to a form view.  Also, renames the
variable 'searchview_drawer' to 'drawer'.
[FIX] correctly display the searchview/drawer (addon web)

the searchview has been splitted in two widgets: SearchView and
SearchViewDrawer.  They are dependent of each other, so a drawer
has to be created for each searchview.  This was not the case in
some form views (inline, created by a wizard).
[FIX] remove an extra border-bottom css rule (addon web)

the border-bottom was set on drawer_container and on drawer,
resulting in a double border.
[IMP] unlink ir.action.todo which are related to actions which will be deleted.
[IMP] better architecture for searchview/drawer

Before, the searchview and the searchview drawer had to be instantiated by
the user and appended separately to their correct place.  Now, the
searchview is responsible for creating/destroying the drawer, and the
user is responsible for correctly using the insert method with
the node where the searchview/drawer are to be inserted.
[FIX] fix the graphview field selection

searchview has been split in two parts, and the inputs are now located
in the drawer
[IMP]: change author and module name
[FIX]: change correct label and fields in Event Analysis.
[IMP] improvements to inline searchview (web)

this commit splits the widget CustomFilters in two widgets:
CustomReports and SaveFilter.  CustomReports is the widget
displaying the list of reports, and SaveFilter obviously is the
Save Current Filter widget.

The goal was to put the custom reports in the first column and the
Save Current Filter form in the second.
--addons-path not required anymore
