Adding the Android-IMSI-Catcher-Detector (AIMSICD)

Good evening @Zegnat and @nylira, welcome to my second pull request in another attempt of closing #1020! I really couldn't sleep after the setbacks in my first pull request in #1069. This pull request does:

* Add our Android-IMSI-Catcher-Detector (AIMSICD)
* Add a new sub-category to the site named "Cellular"
* Add the new sub-category to all language files in `locales`

And if you're looking for the permission of adding the "Cellular" sub-category, you'll find it [here](https://github.com/nylira/prism-break/issues/1020#issuecomment-47182850). @E3V3A, @xLaMbChOpSx and @He3556, would you please open up another champagne for celebration? :smile_cat:
