Hello PA,

##Update NavUI, theme image & footer(Navbar UI #1769)
Closes: #1769

Description

1)The height of the navbar is too much. So, fixed that.
2)Theme image of buddha previously collapse with the navbar. So, I added new theme image & color of text adjusted according to new theme image.
3)At the footer section, the input email box has not given top left and bottom border-radius and also extra 10px margin is removed by me that is of no use.
