Merge lp:~uriboni/messaging-app/stickers into lp:messaging-app

[Ugo Riboni]

Prototype implementation for stickers support.

Prototype implementation for stickers support.
At the moment only the sticker picker component is implemented (including the most frequently used stickers panel).
Actually sending the sticker chosen by the user is not implemented by this branch yet.

It is also unclear what stickers will be preinstalled, so at the moment the app reads stickers from the user data directory: ~/.local/share/com.ubuntu.messaging-app/MessagingApp/stickers

Each subdirectory is considered a "sticker pack" and the pack can contain any number of png, webm or gif files, preferrably with transparency.

Test sticke packs: http://people.canonical.com/~bfiller/stickers.tgz

+    \brief List model that stores information about most recently used stickers
+
+    StickersHistoryModel is a list model that stores information about the most
+    recently used stickers.
+    Each sticker is simply identified by the sticker pack name plus the name of
+    the sticker image file itself.
+    Stickers are ordered by the time of last use, with the most recent first.
+    By default the model stores a rolling list of the 10 most recently used
+    stickers, though this number can be changed by setting the /a limit
