Visualization in Job Shop Scheduling Problem View doesn't get refreshed when changing problem instances

r10213 fixed refreshing of visualization in job shop scheduling problem view

This still does not work. I can add new jobs to the list which are not reflected in the view, I can change parameters of the jobs and the tasks and they are unrefleted. Job and Task both do not seem to throw ToStringChanged events.

Also I noticed the tab order is wrong in those views.

r10433:

• Fixed tab order in JobView and TaskView
• Added additional events and registriations to account for changes to the jobs and tasks

I noticed that we have some overrides of Equals and GetHashCode in Task and Resource. Especially the override in Task creates problems because it uses mutable properties to calculate the hash code. The ItemListView<Task> doesn't update when the task's ToString changes, because then also the hash code changes and it can't find the associated ListViewItem. I didn't address these problems yet. These problems were solved by removing the overrides in Task.

r10476:

• removed Equals() and GetHashCode() overrides as well as related static methods.
• changed ctors of Task and Job to prevent calling virtual members.

r10494: fixed failed unit tests after removal of equals / gethashcode methods in schedule encoding.

Reviewed and tested r10433, r10476, r10494. Seems alright. I will merge it into stable.
