Create custom BriarRecyclerView and use it for the contact list.
It is a common pattern to have a list with an empty view and a progress bar.
This commit introduces a custom BriarRecyclerView and uses it for the
contact list.
No more manually hiding and showing empty views and progress bars is
necessary when using the new BriarRecyclerView instead of RecyclerView.
Please note that this conflicts with !44 at the moment and needs to be
implemented for !36 once merged.
Closes#198

Overhauled Conversation View with Message Bubbles
The Conversation View now uses a RecyclerView with conversation bubbles
in alternating colors and vector drawables to indicate message state.
The conversation bubbles have been taken from Telegram
and can be replaced by a UX designer later.
There's also a special bubble for unread messages,
so they are not overlooked when they come in delayed.
This commit also addresses #9, because message text can
now be selected and copied. This is done by using
android:textIsSelectable="true"
which only works for API level 11 or higher.
If we want copy and paste on lower API levels,
additional measures have to be implemented.

The button hides itself when you scroll down the list of contacts
and shows again when you scroll up.
To properly color the button, the accent color has been defined.
It uses the same color as the action bar (primary color).
I leave it to a UX designer to adapt the color scheme.
Please note that the design support library was used.
It includes the app-compat library, so this has been removed
from the `build.gradle` file.
Closes#199
properly notify the view adapter of dataset changes
in order to avoid invalidating the entire dataset when not absolutely necessary.
This change also shows unread messages in a different color,
so users do not fail to notice delayed messages.

When you receive a message from a contact,
it will be moved to the top of the list with a nice animation.
Also with this commit, not the entire data set is invalidated each time data changes,
but only the parts of the data that really require an update.
Furthermore, the ContactListItemComparator that is not needed anymore is
removed.
Layout tweaks for ConversationActivity.
Centre the progress wheel and empty list message, hide the empty list message until the list has loaded.

Remove the Toast that always says 'Message Sent' and show graphical
indicators instead that show either:
* message is waiting to be sent
* message was sent (or requested)
* message was delivered
