patch #1450307 - option for select all to work in layer with it's sub-layers:

* Replaced check-box in preferences with 3 radio buttons (in all document in current layer only, in current layer with sub-layers)
* Altered "Select all" functionality to include objects in sub-layers (if preference is on)
* Altered TAB functionality to include sub-layers (had to introduce "context layer" concept in Selection class - without it TAB'ing would end in deepest child, but it needs to return to parent on subsequent TAB key press)
