Alerts List and Alert View

@andresamayadiaz 

Odesk went down earlier.

BR-6 is almost done, except those two parts:

- search filter at bottom (on going)
- display most recent 10 alerts at the top right of notification bar. (Should be quickly)

But if you're in hurry to release, feel free to merge BR-6 branch, I'll push the rest in my morning. Otherwise, I'll keep updating this PR in the morning.

Feel free to give review or feedback.
