get_tree: default values

Added default values for all nodes, because the i3 get_tree always returns
all fields inside the json objects.

Add geometry and window for views. Window is only availabel on
x11 windows otherwise it's NULL.

Calculate percent only if parent is not empty to avoid division by 0.
