Include the AppData file for Chrome and Chromium

Add the two AppData files, one for Chromium and one for Chrome. The Chrome one
will be filled with the information from the common/google-chrome/google-chrome.info
file and should reflect the current channel (stable, beta, devel). On the other
side the Chromium one should be a general one and it will be reused by
distributions that are packaging the Chromium themselves.

For AppData specification please see:

+    Chromium is an open-source browser project that aims to build a safer, faster,
+    and more stable way to experience the web.
+    </p>
+    <p>
+    We invite you to join our effort to build a powerful platform for developing a
+    new generation of web applications.
+    </p>
+    <p>
+    Chromium supports Vorbis, Theora, WebM and HTML5 audio and video standards, but
+    does not include the non-free AAC, H.264, MP3 or Adobe Flash code that is found
+    in Chrome.
