Start the overhaul!

I would like to really get this repo to look good for users starting out with the UI Element. Right now, it just seems to cluttered and clunky. I've decided to start making some changes. First got off with these few:

- [x] Remove numbers from script names list
- [x] Change the overall format of readme
- [x] Remove .txt files **
- [x] Create a GitHub wiki for the repo
- [x] Remove duplicate scripts that do the same thing
- [x] `Untitled 1.py` and `Untitled 1.pyui` were renamed to better fit what the script does.

** `Untitled 1.txt` was removed especially because in 1.6 (currently in beta, you can [sign up here to get it][1] if you haven't already) when you create a script with UI, it automatically calls and loads it for you. 

I'm not done yet, and I hope to get a lot more done. Here's what I would like to get done:

- [ ] Categorize scripts into folders based on Basics, Advanced, Etc. or Tables, Labels, Etc.
- [ ] Comment in the scripts what each line (or every few lines) what actually happens
- [ ] Use the GitHub wiki to host and create new tutorials to build on existing scripts rather than edit them to do the same thing
- [ ] Improve descriptions of scripts (Not fully finished yet, but getting there)
- [ ] Unify Variables throughout all scripts (ex. instead of `view = ui.load_view()` in one script and `v = ui.load_view()` in another, just use view to make the examples easier to follow (Also started)

Hope you agree with these changes. I would be willing to do them all myself if needed.
