Hot corners: Do not suspend, Suspend to RAM, Suspend to Disk

### Problem

My previous OS also had hot corners, and the most useful ones gave quick access to suspend options. Useful because

1. quickly accessible, so suspending (battery saving, energy saving) is nearby
2. watching video without the desktop falling to sleep

### Proposal

Add hot corners for options like

* **Do not suspend** with the mouse cursor in this corner
* **Suspend to RAM** as soon as the mouse cursor hits this corner (back up without password)
* **Suspend to Disk** as soon as the mouse cursor hits this corner (options with/without password, if possible)

### Prior Art (Optional)

From the previous OS, this is a description:
