[OS] FizzOS (Colors and program browser!)

FizzOS!
Version 1.1
FizzOS is an operating system by me and only me.
I've sort of disliked the fact that I have to type everything in computercraft, so I thought I'd try to fix it.
I decided to make an Operating System!

This operating systems best features include:

• No typing commands, just menus.
• Colorful.
• Program Browser.

My to-do list:

• A login system (probably)
• A settings screen (maybe)
• Networking (very likely)
• Themes (maybe)

I am open to ideas and suggestions!

Changelog for 1.1:

Spoiler

- Made the diskdrive icon only show up if there is a floppy disk in the drive, not just if there is a drive.
- Added VERY basic networking (well actually, basically a ping program)
- A few other small bugs that I noticed.

To get FizzOS:

• With the HTTP API enabled type this in a computer: pastebin get pjrDi9cr FizzOS (I think, to be honest, I haven't even used the pastebin program before, but I think that is how it works.)
• Copy and paste the source code into a file and save where ever you want. Source code: http://pastebin.com/pjrDi9cr

Notice: Some programs in the program explorer may show up red, this means that they have been disabled because they cause problems when running in FizzOS, like the clear program, thats blocked so it doesn't clear the program explorer, FizzOS is blocked so you can't run FizzOS in FizzOS (although it works), and a few others are blocked. All blocked programs are: alias, cd, shell, lua, clear, FizzOS.


Controls:
Most of the controls in FizzOS are just up, down, left and right arrow keys.
On the program explorer, press backspace to go back (its noted there anyway)


Oh, and the diskdrive menu item, will show up when a diskdrive is connected, currently, it does nothing except for show an screen saying "incomplete".

The terminal menu item is just the stock LUA program.

Shutting down screen:


EDIT: The loading screens are just for looks, don't worry, the startup one goes for about 1 second and the shutdown one goes for about 1 to 2 seconds. If you really want me to I will delete them.

A good start.
