Add display message support for rooms

[abishekvashok]

Since, we got a rooms fragment which displays all our rooms, we now would need to view messages from them.

• Add onClick attribute to the dynamically generated views which opens a new fragment.
• Pass the room id to the other fragment.
• If network is available try to get new messages and populate the realm table for messages.
• If network is not available and no messages are there in the realm db, redirect to network connection page.
• If no messages are in the room even after there is an internet connection, show it to the user.
• Get the messages from the realm db sorting it with id of the row.
• Display the messages in a recycler view.

Difficulty: Hard
