Execute Toolbar Process on Multiple Records

It is good idea have support for executing process on multiple records in Grid view. Same is requested in past https://groups.google.com/forum/#!topic/idempiere/YDnr8nCFGyA

I suggest to implement this as below
set Record_IDs when process invoked from toolbar in grid view and there are multiple records selected. Process designed to execute on multiple records will check this parameter and if presents then work on it other wise use Record_ID
