Location File Subsampling

Knee deep in location sub sampling today. This is where you can save a sample of a location file, functionality accessed through the modify button then clicking OK and Sample (I think this is a little awkward and would love to hear suggestions for a more obvious place).
In order to get this working, I have written a new version of the Selection screen, one with neatly laid out controls and consistent styling. The functionality remains the same but I have found a bug: if more than one LAV selection is specified e.g. both Activ and Day in the blackbird loc file, only the last selection is applied. This is now fixed!
