* IDEMPIERE-4653 Improve timeout handling of window tab
* Fixed a problem with IDEMPIERE-4130 that was not using role max query records
* GridTable was throwing NPEs because the arrays were disposed before closing
* Lowered log level on MRole to avoid clogging the console (I was testing with INFO level)
* Added more points of control for the timeout exception to give meaningful errors to the user and allow refining the query without closing the Find dialog
* Implemented a control to avoid repeating a slow initial query every time the dialog is open
* Added dialog when the find criteria doesn't return rows and allows the user to refine the query
* When the initial number of records is unknown, show a question mark instead of the count
* * Fix wrong role level pushed in first commit
