Read settings after applying defaults

Browse Source 
Default settings are used as a base and only settings specified in `htoprc` are
applied on top of it. This patch removes the special case for applying some
defaults  when the config does not contain a `meters` key. All defauls are set
before any attempt to read settings, so only keys actually present in the config
file are overridden.
