Providing sane defaults in order to use the template with no additional configuration at all.
At the moment you can't just do
```
hugo new site mysyte
cd mysyte
git init
git submodule add https://github.com/panr/hugo-theme-terminal.git themes/terminal
hugo server -t terminal
```
because FullWitdthTheme and CentralTheme params are not set.
```
themes/terminal/layouts/_default/baseof.html:10:23": execute of template failed: template: _default/terms.html:10:23: executing "_default/terms.html" at <$.Site.Params.FullWidthTheme>: invalid value; expected bool
```
With this little fix the theme starts with no additional configuration than the standard one created by hugo cli.
