Adding further String helpers

[Andras-Csanyi]

Hi All,

I'm using this package and I like it very much, however, I miss the String.Substring helper. Should I feel free to open a pull request containing this helper? Is there anything I need to be aware of which is contribution related beside the usual things? Usual things: clone the repo, create your branch, make your changes, test them and open the PR, etc...

@Andras-Csanyi Yes you can add this, also add a unit test to test the helper itself and to test the helper in a template.
