Better commands name

[lnc3l0t]

I think prefixing the plugin "name" is better than suffixing it.

Let's have the commands become:

• CreateGist -> GistCreate
• CreateGistFromFile -> GistFromFile
• ListGists -> GistsList

I think the commands may be more easily remembered

LGTM I'll do a pr by the end of the day, I think i'll keep old names for this release and remove them in the next one. In order to let people easily migrate. (maybe with a warning)

Nice! If you want to focus on something else I'm doing a PR myself, but I'm focusing on the other issue #10 first

Uh! Thank you!
