give snippets clearer names, remove unneeded snippets

I think the last commit to your library was about two years ago, so I'm not even sure if you are maintaining it. Nevertheless, I find the snippets useful.

However, some the names didn't describe the snippets clearly. Of the unclearly named snippets, I found many unneccessary. They belonged to an auto-complete system meant for completing short fragments rather then a template system intended for larger sections of code.

I'd love to know what you think. I hope these changes might be useful to you and/or others.
