Themes are now saved when you select one.
There are currently 5 themes for selection but one works as of now.
(Google Now). It requires you to close the app to view changes but I'll
update that later. I'll also update the default look later on. (Unless
you actually like it. o.0)
Added method for checking if unlock key is installed.
Gave the default theme a makeover and fixed the issue where user input
wouldn't show upon using the Google Now theme.
Added application icon. Let me know what you think.
