Changlist:
- Added Jim Palmer's well proven natural sort algorithm.
- Added natural sort license (MIT).
- Use natural sort everywhere inside TableWidget.js wherever we use .sort()
- Changed browser_storage_overflow.js so that the test is faster and more maintainable. The test now also tests column sorting (ascending and descending).
- Use natural sort everywhere inside storage.js wherever we need to slice the array. Without natural sort here we get e.g. row-1, row-10, row-100, row-2 etc.
