/*
* 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
