Title: [B] Added method to check if Material is interactive. Adds BUKKIT-4747

##### Justification:
Simple way to check if Material is interactive. If player interacts with block (chest, bed, door, anvil, comparator, lever etc.), you can easily test if material is interactive and for example cancel interaction.
Method does not check for blocks that need item for interaction, like grass block (use of bone meal creates tall grass), cauldron (use of empty bottle fill it with water or use of bucket with water fill cauldron), End Portal Frame (use of eye of ender activates portal), sapling (use of bone meal creates tree) etc.

##### PR Breakdown:
This PR is adding one new method that allows to test if Material is interactive, which means that player can interact with it by default.
