Handling misfires using batch commands

[nicsur]

Handling of misfired triggers using database batch commands. The goal is to minimize database round-trips to reduce handling time when there is a large number of misfires.

• New boolean setting: quartz.jobStore.batchMisfireHandling to control feature.
• When batchMisfireHandling is set, the misfire handler will process misfired triggers in batches of size maxMisfiresToHandleAtATime
• To support batch processing of triggers, multi-object methods have been added. They mirror the exiting single-object methods.
• The single-object methods are kept as they are for backward-compatibility.
• Not all supported stores can handle batches and this is controlled in code by IDriverDelegate.SupportsBatching override.
• Unit-tests and tests have been added to cover the changes.

Sorry for keeping you hanging. Could you please rebase against master and I hopefully have soon time to go through this idea. Thanks for understanding.
