[FIX] bundles: fix compiled css assets recomposition

- Do not include css in less source because malformed css will break
  less compilation
- Always recompose compiled css, even if not in debug mode
- Less and sass compilers mode @at-rules on top in order to comply
  to css 2.1, those @at-rules where left-over during the recompostion
  because they lost their marker. Those are now handled as virtual
  inline stylesheets.
[FIX] ir.attachments of compiled css assets not properly invalidated
Update __openerp__.py
