Attempt to provide a solution to bug #14399 by defining a new property with which we can set a timeout for the execution of a conversion task. By default, the timeout is set to 120000ms (2mn) but a greater value can be required on Windows as this system is a true bloatware.
The bug coming from the pagination was operated two times: - one by the web controller, - one by the ArrayPane itself. The fix has been to remove the pagination in the web controller side and to leave ArrayPane to controle the pagination of tikets.
