#2 Categories

[Tamas Ragoncsa]

It would be good to have categories for the tasks. It should be something like a grouped list where the individual groups can be opened and closed. It could be showed how many items the category contains.
It would be nice to add this as an optional module to keep the basics simple and easy. (I.e. without enabling the categories module the category names can be shown in the name of the task - just like a more specific task name)
