ACT-1300/HEMERA-2522: moved writing of HistoricProcessVariable to process end event (not on BPMN end event), fixed name of variableValueEquals

ACT-1300/HEMERA-2522: removed inheritance from HistoricProcessVariable (as it does not make too much sense), removed fields now no longer used from table and accordingly removed conditions from HistoricProcessVariableQuery

- Added informations for taskId and callActivityId
- Updated create/upgrade scripts

ACT-1202: Fixed remaining test case and adjusted to write audit log for start event on level "activity"

ACT-1202: Adding events to HistoricActivityInstance, marked old "getEndActivityId" deprecated and added the explanation why

ACT-1136 Add support for intermediate catching message event

ACT-1046: - Added an interface "FailedJobCommandFactory" and an implementation of it "DefaultFailedJobCommandFactory", renamed "DecrementJobRetriesCmd" to "FailedJobListener" to able to configure a delay between retries and amount of retries;
- Added "parseIntermediateCatchEvent()" and "parseBoundaryEvent()" in BPMNParseListener to allow some extensions to these elements (e.g. specify a specific failed job retry logic)

ACT-1091 ACT-1092 ACT-1093 ACT-1094 ACT-1095 Adding persistent event subscriptions providing  support for signal events, event based gateway, compensation and transaction

 - Fixed bug in ManagementService (manual create schema didn't work)
 - Added method in BPMNParseListener

There are some formatting changes also, but they won't do harm to my opinion

ACT-506: further enhancing and testing multi-instance support. Switched back to ActivityBehavior wrapping behavior instead of nested activities.

ACT-15: added example of boundary error catch to distro. Added drawing support in for error event in deployer. Introduced shortcut to reference errors.

ACT-498 Ensuring that activity history listeners on start event are notified first so that subsequent handlers have access to the historic activity instance

reverting commit 1811 (overlooked test failures) ACT-498 Included active activity instance id on HistoricVariableUpdate when variable is updated

ACT-352 Fixing lazy initialization of historic variable updates.  Also fixed configuration of history

ACT-329 Also enabled HistoricProcessInstance.startActivityId and endActivityId on plain startProcessInstance (previously it was only on submitStartForm)
