Add navigational buttons/icons to template server UI #102
Description
On the server, when the user wants to download more templates, it would be helpful to have:
- an icon like a semi-transparent horizontal double-headed arrow on the right side of the screen to indicate that scrolling is possible to see more languages and templates
- a back button to enable the user to navigate back up a level
- ?? perhaps (at the top of the screen) a brief instructional note in yellow/gold colored font saying "Tap to select"
