#109 Parent combo hierarchical structure

[Aurimas Juška]

Edit task > Parent: combo box currently is not hierarchical and all projects and tasks are displayed in the same level. It makes very difficult (or impossible - if there are many tasks with the same name) to reassign tasks. Therefore, it would be nice if combo box could display items with hierarchical information, for example, Project X / Task 1 / Subtask 1.
