lamassu/lamassu-machine issue #30, updating setup.sh with new urls for f...

...onts, and removing calls to deploy/fonts/install.

* made the mkdir for /tmp/lamassu-fonts always be quiet and a clean directory.

* added command to copy TTF files to ./ui/css/fonts, overwriting any duplicates in the destination 
* added a few echo statements for clarity (I like to know what the computer is doing and when)
