d6bd30f2da IE touch device fix
Add vendor specific css for IE to handle let javascript handle touch events instead of letting css attempt to handle them. Without this CSS property IE touch devices do not work.

ca4d835129 Simplify parseInt.
Because `~~` isn't necessarily faster than `parseInt` in every browser.
Now I think it'd be better to make it readable and simple.

to update the size or position of the scrollbar, just update.

## RequireJS usage
For RequireJS loader, no need to write shim, simply import two libs:
```javascript
require.config({
paths: {
perfectScrollbarJQuery: '.../perfect-scrollbar.jquery',
perfectScrollbar: '.../perfect-scrollbar',
}
...
})
```
and load `perfectScrollbar` in the initialiser of your app:
```javascript
# for vanilla JS:
window.Ps = require('perfectScrollbar');
# for jQuery:
require('perfectScrollbarJQuery');
```
## AngularJS + RequireJS usage
With the require.config settings above, at the beginning of your app module
definition, you can have following code:
```javascript
define([
'angular',
'perfectScrollbar',
'perfectScrollbarJquery'
],
function (angular) {
var myApp = angular.module('myApp', [])
.run(function() {
window.Ps = require('perfectScrollbar');
require('perfectScrollbarJQuery');
})
return myApp;
});
```
And initialise perfectScrollbar in a controller:
```javascript
# by vanilla JS:
var container = document.getElementById('imgLoader');
Ps.initialize(container);
Ps.update(container);
# or by jQuery:
var imgLoader = $("#imgLoader")
imgLoader.perfectScrollbar();
```
## Optional parameters
perfect-scrollbar supports optional parameters.
