Improve the README

[AdamNiederer]

• Add a MELPA Stable badge
• Remove the unnecessary (require 'vue-mode) section
• Ensure elisp code is properly indented
• Clean up the spacemacs section
• Clean up the Q&A section
• Add a section or point about our new indirect editing functionality (M-x vue-edit-indirect-at-point)

Help on any of these points would be greatly appreciated.

As mentioned earlier, I'd like to help with the README in regards to spacemacs. My main problem currently is that I'm not sure what functions vue-mode actually has in terms of vanilla Emacs and whether my current spacemacs setup is running correctly. Mostly it's my problem with indentation that I can't seem to solve.

vue-mode is really just a thin wrapper around mmm-mode. It provides syntax highlighting, indentation, and a few helper functions (edit indirect functionality is the big one). We rely on other packages in the emacs ecosystem to do autocompletion, linting, and most other things you'd expect out of an IDE.

I'm currently in the process of fixing most of the indentation issues; I'd just like to do the whole thing in one go b/c of personal time constraints. Most indentation issues are probably bugs on my end, whereas others might be configuration issues. Have you experienced any erroneous indentation other than the currently-filed issues?
