Be able to add custom item types

[aidanhorton]

The ability to create custom item types (item, bug, task, parked, investigation etc...), and also assign them a colour.
Not sure what the UI would look like for this, but I'm sure this could be figured out ;)

Approved. Think we could do this as part of a settings overhaul, at the moment there's no settings menu and this could be crucial. Few things we'd need to figure out however, would the items share across boards or would they be exclusive to each board and also lots of testing would have to be done.

@Swegrock I've attempted this a bunch of times, but I can't get it to look quite right, honestly I think I need your UI prowess here.

If you need a colour picker to let the user pick a colour for a task, use the Extended.WPF.Toolkit from Xceed, and use the ColorPicker class, you may want to set the ColorMode to ColorCanvas too, it's a litte more user friendly!

If you don't fancy this one then let me know and I'll soldier on through it and see if I can get something decent.
