Add if rule

[eadm]

Add rule to check if semantics.

Good
Default semantics

val x = 
    if (a > 13) {
        100
    } else {
        500
    }

One line semantics (if line shorter than 100 symbols)

val x = if (a > 13) 100 else 500

Bad

val x = if (a > 13) 100
else 500

val x = 
    if (a > 13)
        100
    else
        500
