New layout: tabbed

This will allow us to provide a more friendly interface, with
easily accessible information and settings.
switched main view
added new strings in English for new layout
Application fragment

Now it shows up two separated lists, one for enabled application (i.e.
the one we want to make through some Proxy), and disabled.

Missing: actions.
We have to do some more dev in order to get the following capabilities:
- user touch an app, it should go to the right listing, and iptables
  rules should be updated
- for enabled app, we have to add a new visual in order to let the user
  access advanced features

Also, for "home" tab, we must update display in order to use the
application settings.
added some debug
I was told "dark theme is bad".

Indeed, it may prevent some people to read things. More over, the "all
dark for hackers" may prevent other people to just try the app, as
"hell, it's all black, run away".

Thus… going to "light" theme.

using CheckBox in order to get a visual return, and an access to isChecked method. #lazy
