New Rules: disallowOperatorBeforeLineBreak

Closes gh-511
I see three ways to workaround that:

1. Create new rule, specially for dot symbol
2. Detect when dot is used as binary operator and apply the check only then
3. Add dot as binary operator and rename the rule in 2.0 by replacing word "Operators" to something like "Tokens", we're iterating on tokens here anyhow
