Changing the theme and adding a new login.ztml

Added d3c0y's login.ztml and the files needed to make it work.

Added <# ui_tpl_assetfolderpath #> to the master.ztml in all places needed as it's a better standard to use instead of having it hard coded in.

Added <# ui_tpl_year #> to Copyright as it was also hardcoded with the date.
