Cleaned up a couple things with chat

-TextView automatically pushes down to newest chat
-Cancel button clears text field
Made some changes to the text fields

-Return buttons now say done
-Keyboard resigns when clicking on background
-Now able to clear profile text fields with button
-User name automatically sets to device name if no name is set

--Also tried adding a method to fix the nag bar height…doesn't seem to
do much.
Added a guest view profile controller
