Don't repeat this code so many times:

```javascript
function make() {
  return Make({
    apiURL = "", // This should read from a textbox on the page with a default value of makeapi.mofostaging.net
    auth: username.value + ":" + password.value
  };
}
...
make()
.tags(...)
...
```
Let's add a textbox to the page so you can enter a new URL for the api end point vs. having an empty string.
