Proposal: Disallow needless `else` statements

[tunnckoCore]

Enforces more clean code. For years I have very rare cases when I need else or even else if statements.

Fixable, no-else-return

This seems overly prescriptive to me.

@tunnckoCore Thanks for the proposal. This rule would disrupt the way that too many people write code and it doesn't prevent bugs or improve code consistency enough to justify the cost to users, in my opinion.

Here are the results of the test suite:

# tests 238
# pass  213
# fail  25

10.5% breakage is too high to really even consider a change like this.

Daaamn :D Okey, no problem. We only can hope these numbers to get low in time.
