Changed "if" statement formatting.

- Keep `else` on the same line as the braces.
- Force braces for if...else statements.

This automatically turns this (and other variations thereof):

```php
// Boo!
if ( true ) return true;
else return false;
```

into this:

```php
// Yea!
if ( true ) {
	return true;
} else {
	return false;
}
```

Previously it would end up one of these two ways:

```php
// Not great.
if ( true ) {
	return true;
} 
else {
	return false;
}

// Horrid!
if ( true ) {
	return true;
} 
else return false;
```
