LTSleepNStorm-0.2.0.jar

A public API were added. Developers can easily hook into LTSleepNStorm now. Javadoc is available here: https://leothawne.github.io/javadocs/LTSleepNStorm/
Added an AFK mode: I added an AFK mode called "Rest Mode". If you stay still for 300 seconds (default timeout), the rest mode will automatically be activated until you move or you do something.
And the "Rest Mode" prevents you from getting tired while you are AFK.
New mechanics added: I added a "fatigue system". It will only be possible to sleep if the player is tired enough. This new mechanic can be disabled with the new permission node: "LTSleepNStorm.sleep.bypass". Fatigue is disabled to OPs by default.
Each bed will now check if it's obstructed: I thought it would be important to check if the beds are obstructed before they are used. It wouldn't be nice to sleep in a bed with a stone on top or something.
Consumable items added: I added coffee. As soon as the player drinks the coffee, he will gain extra energy. The more you drink coffee, more time you will get to be awake/not tired. Recipes will be available here: https://leothawne.github.io/LTSleepNStorm/recipes.html
New commands added: "/sleep" can be used to force yourself to sleep anywhere without a bed. The command is allowed to OPs only by default. You can override it with this permission node: "LTSleepNStorm.sleep.command".
I also added "/restmode" (or "/rm"). It allows players to toggle its own Rest Mode status.
