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
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.
