Added plugin support for1.9,1.10,1.11,1.12

Note: 1.12 and below has known issue with animal feeding infinite items.

Note: code Is in plugin to test for 1.13 and 1.14 but java version on my pc is to high to be able to run a server in these versions. If you can test the plugin in these versions feel free to contact me and let me know what you find.

Added “/infinity” command which allows you to toggle on or off the item pickup mechanic of the plugin.
