Added support for environment variable substitution

Browse source 
* Only environment variables starting with HOMEPAGE_VAR_ and HOMEPAGE_FILE_
  are supported
* The value of env var HOMEPAGE_VAR_XXX will replace {{HOMEPAGE_VAR_XXX}}
  in any config
* The value of env var HOMEPAGE_FILE_XXX must be a file path, the contents
  of which will be used to replace {{HOMEPAGE_FILE_XXX}} in any config
* If a substituted value contains a variable reference it may also be
  replaced, but the behavior is non-deterministic
