Added some new placement options as per request.

1. Created Loaders can now be placed on a grid (every nth loader the placement will start over on one axis and step one position further on the other axis.)
   Setting grid placement to 0 or 1 makes the script behave in the old way, setting the grid placement to 1 however reverses the placement direction (obviously.)
2. Placement on y-axis can now be set to tiled, so when loaders are set to force source they won’t overlap anymore.
3. Script settings are now stored in between session.
