Hob: remember layers and settings between Hob sessions

This patch is to remember layers and settings between Hob sessions, which
includes:
 - Put some variables for the build details screen from Configuration to
   Parameters because they are not actually for build but for show
 - We create a dummy Configuration instance and a dummy Parameters instance
   in __init__ of builder
 - The two instances will be assigned the real values by
   update_configuration_parameters() after parsing (in the event callback)
 - When it is the first time to launch Hob in a build directory, nothing is
   remembered since everything is fresh.
 - The feature is implemented with templates, and based on the hook for Hob.
 - When the user changes the layers or the settings, a default template file
   is saved into ".hob/".
 - Later on, the layers and the settings are remembered by loading the default
   template automatically.
