Issue #2167505 by ianthomas_uk: Call to undefined function drupal_container() in config_inspector.module on line 55.

Issue #2044739 by Jose Reyero, Gábor Hojtsy | vijaycs85: Start converting menu callbacks to routing system

Issue #2066997 by juanolalla: Fixed Form inspector shows undefined method DataType\Boolean::getType() error.

Add permission for controlling inspector access so we are not hit with a disclosure security issue :) Even if the whole module is only meant for developers.

- Move unused code at the bottom of the module so we know what is in use; the code kept might be useful later (context and translation inspection)

 - renamed module from config_demo to config_inspector
 - more user friendly module description, name, etc.
 - restructure URLs so tabs can be used to navigate around
 - remove translate option even if locale is enabled given we don't yet have that supported (http://drupal.org/node/1905152)
 - fix raw data dump page to actually dump the raw data for the given config key

(List and tree page not working yet)
