Add support to display regulatory info from *#07#. 

Add a new action and Activity so the phone dialer can display
regulatory info via "*#07#".

Regulatory info is supplied per device by a Settings app resource
overlay. This overlay must set the boolean resource
"config_show_regulatory_info" to true, and provide either a drawable
named "regulatory_info.png" with the info in graphical form, or a
string resource named "regulatory_info_text" containing the required
information in HTML format.
