/*

 * IMCE Integration by URL

 * Ex-1: http://example.com/imce?app=XEditor|url@urlFieldId|width@widthFieldId|height@heightFieldId

 * Creates "Insert file" operation tab, which fills the specified fields with url, width, height properties

 * of the selected file in the parent window

 * Ex-2: http://example.com/imce?app=XEditor|sendto@functionName

 * "Insert file" operation calls parent window's functionName(file, imceWindow)

 * Ex-3: http://example.com/imce?app=XEditor|imceload@functionName

 * Parent window's functionName(imceWindow) is called as soon as IMCE UI is ready. Send to operation

 * needs to be set manually. See imce.setSendTo() method in imce.js
