LANG-848: Added isAnyBlank, isNoneBlank, isAnyEmpty, isNoneEmpty

Those are the improvements described in LANG-848 including 
```java
public static boolean isAnyBlank(CharSequence... cs)
public static boolean isNoneBlank(CharSequence... cs)
public static boolean isAnyEmpty(CharSequence... cs)
public static boolean isNoneEmpty(CharSequence... cs)
```

furthermore i implemtented the missing tests for isBlank, isNotBlank, isEmpty, isNotEmpty and the new calls.
