Allow filtering of Task dependency types in Task & Calendar views

With the new task dependency filter, it would be helpful to build a filtering capability in the overall Task and Calendar views. The most pressing filter needed is (1) below, but the others would be helpful:

1. **Allow mirrored tasks to be filtered in Task and Calendar views**. Right now, I am not using mirrored tasks as much because they clog up the Task and Calendar views with "duplicate" entries. So, filter on something like "only show source mirror tasks", something like that.
2. Show either only the Goal tasks, or only the Implementation tasks, or both.
3. Show any task that has "basic" task link
