GUACAMOLE-310: Fix clipboard handling of newlines.
As reported in
[GUACAMOLE-310](https://issues.apache.org/jira/browse/GUACAMOLE-310), newlines
are being stripped from clipboard data copied using the [W3C Clipboard
API](https://www.w3.org/TR/clipboard-apis/). This makes clipboard use
cumbersome for users where the browser provides direct integration of the
clipboard, such as IE11 or Chrome with the [Clipboard Permission
Manager](https://chrome.google.com/webstore/detail/clipboard-permission-mana/ipbhneeanpgkaleihlknhjiaamobkceh)
extension.
This is due to newlines being stripped from `textContent` of a `<div>`
despite `white-space: pre` being set. As this did indeed work before, this
seems to be a recent browser behavior change. By reverting back to using a
`<textarea>` the clipboard event target, newlines work as expected.
