Slightly improving docs for explaining electric returns

[szmer]

I've just started experimenting with Slimv coming from Spacemacs. I was a little surprised when I saw enclosing parens moving to new lines when I enter a newline. I kind of guessed the purpose (exploiting vim line editing features, yy, dd etc.), but it was not clear how to then automatically reformat the code "right". I imagine some completely new person could think that this is how Lisp code is supposed to be indented.

Then I found some SO questions where you mention electric return, and then this question with a looong gif which gave me the idea to input the closing parens manually and then they will reformat instead of appearing.

So I think some changes to docs could save users some confusion:

• in the tutorial you link an animation that should explain the feature, but the link to ImageShack is dead.
• I now know that this is a Paredit feature, but if someone unaware searches the Slimv help for "newline", "parentheses" etc. they will find nothing directly helpful. Maybe near the fragment "First of all there is paredit mode" you could mention to people that they can read more about paredit mode in its own docs (where actually the thing is decently explained).

Ah, thanks for pointing out that the animgif link in the tutorial is dead. I changed it to a local copy. I'll also revise the docs.

Also updated the docs: added new tags on |newline|, |parentheses|, updated comments on electric return, fixed gif link in doc. See commit https://github.com/kovisoft/slimv/commit/e0dc4eb5e55700d70e1bb73b14152b23816122e7

Thanks, my scenario at least now seems to be well covered.
