Simple Implementation of Searching.

This is a very simple Implementation of searching like playlist view
and file view there is an boolean value that is checked in the draw
function to check if whether or not to draw the Search view
Later on I am thinking of rewriting this whole mechanism with pages
which will make this more modular.

The Boolean values are set and unset by the navigation menu and the done
functions.
