[oXygen-sdk] Check out a resource during Replace All

[Oxygen XML Editor Support (Radu Coravu)]

Hi Jeroen,

I agree with your findings, indeed somehow I wanted to give this 
callback before Oxygen actually starts to read the URL's contents, but 
before Oxygen starts reading the URL's contents it does not know if it 
will make changes to the contents so right now although the callback is 
named "aboutToModifyResource(BatchOperationInfo, URL)" we give it for 
each resource.
So this is definitely not OK. I will add an issue on our side.
Maybe for now you could detect when Oxygen calls your URL handler's 
"getOutputStream()" method. This means Oxygen is about to write to the 
file. If before "getOutputStream()" is called you also had a call of 
"aboutToModifyResource(BatchOperationInfo, URL)" for the same URL, this 
means that you need to check out the file (on the "getOutputStream()" 
method).
So you should move the file checkout from "aboutToModifyResource" to 
"getOutputStream()".

Regards,
Radu
