Add "flamethrower", "exhaust" and "exhaust_diy" thruster effects (#3231)

* Add entity:parentToAttachment()

* Fix design oversight on timerSetDelay.

* removed unnecessary logic

* Added "exhaust" and "exhaust_diy"

* Flamethrower effect & pictures

* Revert "removed unnecessary logic"

This reverts commit a722a5e746.

* Revert "Fix design oversight on timerSetDelay."

This reverts commit e9fe870989.

* clean up flamethrower effect
