[FIX] web: notebook: remove fade effect on tab switch

Also, fixed two global variables introduced by rev b2e32a8f7e7d0b
[FIX] website_blog : identation problem, and unused variable
[FIX] web: makes last breadcrumb item clickable

[FIX] web: fix various syntax problems in views.js

linting views.js revealed some problems.  Most of them minor, but
some of them more serious: redeclared variables in if clauses can
shadow the outer variable, or not.  It is fragile, and will cause bugs
if the code is refactored.
[IMP] purchase_requisition : onboarding of purchase views
[IMP] mrp: more explicit labels for "BoM type"
[REM] mrp: removal of group_route_line_type

This group was used only to hide/display the type (normal or phantom) of BoM lines.
Adding a group to hide/display 1 field seems overkill.
[FIX] product_extended: incorrect inheritance

This view was intended to extend the tree view of mrp.bom, not
mrp.bom.line. Nonetheless, the view mrp.mrp_bom_tree_view which is extended here is a
view for a mrp.bom.line, and there is no tree view for a mrp.bom.

So this extension has no meaning anymore and seems to have worked only
by accident...
