Title: util.Random.alphanumeric method moves to util.Random class

I want to use util.Random.alphanumeric method to generate a password.

```scala
util.Random.alphanumeric.take(8).mkString
```

however, this is not secure.

so, I tried making alphanumeric possible to be called from java.security.SecureRandom.

```scala
import util.Random._
new java.security.SecureRandom().alphanumeric.take(8).mkString
```
