Close EADS-3585 branch

EADS-3585 - As a database developer I want to easier see what connection I am working with from so that I can develop more reliably
- PlsqlExecuteAction now uses new implementation of PlsqlFileExecutor.
- when using main/template connection, user will get one connection from pool for each editor window
- now using same IO for both execution action and for transaction actions (commit and rollback)

EADS-3597 - use NB way of showing connections instead
added new executor to lookup of DataObject, to access connection.
added JComboBox with projects connections (instead of add in to execute DropDownButton
changed PlsqlExecuteAction to use new executor
todo: debug is no longer working

Deploy Selection in PL/SQL files seems to be broken

Select statements that contains CASE statements don't execute

fixed tests to make Jenkins job pass
EADS-3496 - Select statements that contains CASE statements don't execute

increased RequestProcessor throughput, could not notice any side effects
EADS-3700 - Not able to execute more than one thing at the time

will check for open session when deciding if a transaction is open or not. instead of just looking in the executed code to see if some DML commands are used.
some refactoring done, more needed.
EADS-3602 - Transaction buttons does not get enabled when executing code that should leave transaction open/pending

Removed changers from - Select statements that contains CASE statements don't execute
