YN-0142: Launcher workfile tab improvements

[antirotor]

The launcher now having the option to select a workfile is a welcome update, I would just like to suggest a couple of updates:

Add in the workfile's date as an additional column, Add the option / another collumn showing the DCC to be able to sort by DCC/filetype (its quite a mess when you are using multiple DCCs for the same product)
