Fix issue#23 by adding translate(0) to scooch items.

Status: **Ready for merge**
Reviewers: ** @scalvert **

## Changes
- Adds transform: translate(0) to items within a scooch to work around the following webkit bug: https://bugs.webkit.org/show_bug.cgi?id=137313

## Upgrade instructions for non-bower users.

For users not on bower you should be able to add the following lines...

```
.m-scooch .m-item {
    -webkit-transform: translate(0);
    transform: translate(0); }
```

...in to the CSS for your site (probably where you style scooch).

## Alternative Fix

There is also an alternative fix, which involves adding an empty event handler to scooch's items which can be used if the CSS fix does not work for you.

```
$('.m-scooch .m-item').on('touchmove', function(e) {
    return true;
});
```
