To allow to use a custom upload mechanism in WFileDropWidget (tus), we need a couple of modifications. Changes are minimal, mostly these allow for some overrides/redefinitions.

In WFileDropWidget.js:

• Allow for override of requestsend signal (dropwidget.emitRequestSend())
• Allow for override of dropwidget.getSendFn callback (dropwidget.getSendFn())
• Add parameters to actualSend and workerSend to allow definition from another context

In WFileDropWidget.C:

• Allow custom creation of an upload resource in WFileDropWidget::handleSendRequest() and make it accessible
