Rework of Identity wiki page

[domob]

I've reworked the id/ wiki page (https://github.com/namecoin/wiki/wiki/Identity) a bit to bring it up to date with the current version of id/ I have in mind. What do you guys think about it? I still have to write up the GPG fingerprint specs, which are basically those defined in the "Personal Namespace" page (but I think they should be part of the Identity page). Two things that came to my mind while working through it:

• Why are not at least dashes also allowed for characters? I think we should allow them (as for domains). And what about internationalised names like the IDN domains? I think this makes sense to allow for names in foreign languages, ideally with the same IDN syntax (so that implementations can use the same code, for instance in libnmcrpc).
• Can anyone who knows more about MediaWiki than I do check why there are display problems whenever a square bracket is part of an example code block? It is surely something stupid, but I have no idea how to fix it.

I fixed the square brackets.

I agree that dashes should be allowed. Why restrict id/ at all? Why not allow everything, including unicode?

Thanks for the fix! I expected that using the "code environment" with indentation would already switch off markdown interpretation. I also tried '\[' to escape the square brackets, but it didn't work. Thanks!

I think we should use IDN encoding for Unicode names instead of "plain" Unicode strings (they would have to be encoded anyway, maybe in UTF-8, but then I think it is best for compatbility to use only ASCII chars for encoding--and IDN is something which is already used for domains anyway).
