3Dgoo f948afe271 Fixing non int pagination variable server error
If a user tries to paginate the blog using a value that is not an integer SilverStripe will throw a server error.

Example. Visiting `blog/?start=10.1` will cause the following server error:

```You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '10.1' at line 8```

This change casts the pagination variable to an int before using it.
