Auto-encode query parameters

When using the postmen collection, one of the biggest hurdles is that each Query Parameter has to be encoded manually. Now if you only occasionally using the collection it may not seem like a big deal, but having to constantly right click then encode the values can be quite tiresom.

If the collection would contain the bellow snippet, then this encoding would:
* happen automagically
* can be turned off, if desired.

And it can be defined on the `Project` folder, and inherently every request could leverage it.

```javascript
if (pm.globals.get("PM_DISABLE_AUTO_ENCODE")!=="true") {
pm.request.url.query.each((param) => {
param.value = encodeURIComponent(param.value);
});
}
```
