fixes #8521 - fix classes accessors, copy overrides on host clone

The various 'classes' accessors that are used in the UI for displaying

Fixes #8414 - extracts validators from models

Also cleans up some unused validators looking for trailing whitespace

upgrade foreman to rails 3.2.13

This commit updates from rails 3.0.x to 3.2.x, main changes include:

• Asset pipline support
• cleanup of existing assets (javascript, css, images)

Users who uses foreman in production, make sure that you now compile
your assets, e.g...

fixes #1957 - remove old libvirt hypervisors code

Since foreman 1.0 libvirt hypervisors are now part of compute resources
this patch removes the old code and migrate any existing hypervisors to
be libvirt based compute resources.

Fixed tiny typo in the hostgroup unit test

fixes #724 - Allow default VM specs to be tied to a hostgroup

fixes #35 - Allow hostgroup nesting for puppet classes and parameters

Fixes #366 - Redmine authorization port

This is a major feature which provides RBAC authorization within Foreman
a mental note to myself - never ever work on large commits

added hostgroup test and fixed some assertions

Added Groups to puppet classes, now its possible to associate a host with a group of classes
it also allowed to setup parameters per group and override them in the host level

I've done it late at night, so who knows :)
