Add common preferences
Terminals typically have a number of basic preferences that currently aren't present in Console. These include:
- Select a color theme (palette)
- Custom font
- Terminal bell on/off
The first two are settings you don't just get in terminals - they're also common to text editors and IDEs too - anything where people spend a lot of time looking at monospace text. I think we can expect people to want these here, particularly to control for legibility and contrast.
#27 and #87 are relevant. See also the new color scheme preference in Text Editor.
