Add command page, including DestroyWildDinos and SaveWorld

[jordan-dalby]

This PR adds a command page, two commands have been added as of now:

• DestroyWildDinos
• SaveWorld

There is the possibility for expansion in the future. Though, additional commands may require an input box for args.

Closes #86

Looks great, only I think this list of commands should be under the console, and for #86 I don't think this is implemented here, that issue wants a dedicated wipe button, so you can wipe the server with one button and without manually needing to delete files.

Ah I understand. I'll move them below the console and see about implementing the other feature in a different PR.

Small change included along-side requested changes, changed "clear input" to "clear console" to more accurately represent what the button does.
