Subject: [PATCH] Add BASIC seed script

This commit adds a BASIC seed script to our collection. It uses
[Gambas](http://gambas.sourceforge.net/en/main.html) as the interpreter.
Gambas is available in the apt repositories and can parse command line
arguments and run scripts with a shebang line.

* Add `seeds/basic_seed.bas`.
  * Prints a hello world message.
  * Prints a usage info when passed `-h`.
* Edit the Dockerfile to install Gambas.
* Add Basic to the dropdown in `index.html`.
* Add Basic to `main.js` for syntax highlighting.

Fixes #21
