[imp] Split modules selection from actual installation, add handling of hooks and additionals 

* Hooks are functions executed when a given module has been selected for installation
  - Named ``_if_%(module_name)s``
  - Provided cr, uid, ids and context
  - If they return something, it must be an iterable of supplementary addons to install
* Additionals are module sets to install when a given set of 1..n module(s) is selected for installation
  - ``_install_if`` class member
  - dictionary of {tuple: iterable}, the tuple is the set of modules to check for,
    the iterable is the set of modules to install if the condition modules are all
    present
