String.prototype.trimRight/trimLeft

[Behrang Saeedzadeh]

Another set of very handy functions that in Java are provided by libraries
such as Guava or Apache Commons and in C# are built in, are
`String.isNullOrEmpty(aStr)` and `String.IsNullOrWhiteSpace(aStr)`.

Would be nice if they ES Strings had them too.
