Add padding-line-between-statements rule to eslint

[Pareder]

Added rule to eslint that requires the padding line after block-like statements (if, for, while, etc.). It makes code more readable, especially when there are a lot of block statements one after another.

// Wrong

if(true) {
  // code
}
for(let i = 0; i < 100; i++) {
  // code
}
while(true) {
  // code
}

// Correct

if(true) {
  // code
}

for(let i = 0; i < 100; i++) {
  // code
}

while(true) {
  // code
}
