v9.5 release

Added a few useful features:

You can now feed the player even if the player is at max level (no additional points will be gained in this way).

Conveyor belts now start at 32px length.

You can middle click on items on the ground and items in the product slot of structures to put them directly into the player inventory.

Edit: in v9.6 you can now hold middle click to collect items on the ground. The controls page in the recipe book now also tells you about the middle click.

Edit: in v9.7 it is now possible to delete save_2. There was a bug where the instance array data was deleted when deleting save_2 but other data about save_2 wasn't, and now the delete button deletes save_2 like normal.
