Implement sorting in index.md

[ari-party]

This PR:

• Implements the suffixing of (Implemented) to the links of RFCs that contain **Status**: Implemented
• Implements guaranteed alphabetical sorting, and sorting based on implementation status (implemented RFCs come last)

You can preview this here.
Links don't work on this preview due to root URL differences.

The reason for these changes is the matter of RFC relevance, and to add a form of categorization.

(Should (Implemented) be in the link or outside of it?)

There seems to be an issue, possibly with the use of block quotes:

EDIT It's also on Generic Functions and Generalized Iteration, seems to not be the quotes

@PhoenixWhitefire Thanks for finding. I'll get to it when I can

Sorting should be in order of most recently accepted to least recently accepted. Alphabetical ordering is just annoying and doesn't actually help us find recent RFCs. Like every time I need to check an RFC I go to the PRs tab and hope the branch wasn't deleted.

I'll look into that. Afaik Jekyll doesn't support that by default, would require some git integration
