[FIX] website_forum: respect karma when posting questions/answers/comments + more user-friendly errors

While posting new questions and answers the check
for karma limit was bypassed because it was using
super-user mode: use regular user instead.
Also improve the user feedback when karma level is
too low to perform some actions: post comment,
post question, post answer.
The usability in these cases still needs to be
improved.
[IMP] web client refactoring: action and view manager

large rewrite of action manager, view manager and
viewmanageraction.  The goal is to lay the foundation
for the redesign of the advanced search view.

This commit includes:
* improvements to the display order (no/less flickering)
* large simplification of the breadcrumbs code
* much better html layout for the header (no table)
* bootstrapisation of the view manager
* lots of optimizations/simplification
* a base.css.map, courtesy of the last sass version
[FIX] fixes many issues with the various views

the views don't always return a proper promise, or were
somewhat fragile and broke with the changes in the view
manager.

The pager was removed in the refactoring of view manager. This commit
readd the pager, and improves its rendering to avoid flickering

[IMP] rewrite of search view/view manager

Second part of a large refactoring.  Lots of cleanup, simpler code organization, and it should be faster.

[IMP] integrate mail client actions with search view

The mail client actions did not integrate with the search view.  (it is actually an ugly hack to fake a view manager and instantiate a search view. of course it was broken when the search view was refactored)
[FIX] a few bugs in view_form/view_list

some small stuff...
[IMP] add basic pivot support

The goal is to split the graph view into two views: pivot table view (short: 'pivot') and graph view (with charts).  This patch lays the foundation for that work.
[FIX] make the view editor work

with the recent changes in view manager, it was kind of broken.
[IMP] some cleanups in graph/kanban views

notable: disable the group by integration in graph view, because of crash (the search view was rewritten and too much search logic was in the graph view.  This is a temporary measure, the graph view will be split into pivot/graph views, and the search integration will be done correctly in the near future.
[IMP] various code cleanups

remove some old cruft
[FIX] update the search tests

The search tests are totally outdated since the search view rewrite. This commit update them to the new search view.
