Determine data directory.

Let the user choose if the current one doesn't exist. Let the user configure additional preferences such as pruning.

Returns: true if a data directory was selected, false if the user cancelled the selection dialog.

Note: do NOT call global gArgs.GetDataDirNet() before calling this function, this will cause the wrong path to be cached.
