No more disappearing or off-center suns!

I found a simple way to fix the notoriously glitchy suns present in Morning Glory and Death at Dusk.

I have provided an updated version of item_fx.pcf. This version is identical in all respects to the in-game version, save for the following changes:
- "unusual_eotl_sunrise" has been renamed to "unusual_eotl_sunrise_sun"
- "unusual_eotl_sunset" has been renamed to "unusual_eotl_sunset_sun"
- 2 new particle systems have been created, named "unusual_eotl_sunrise" and "unusual_eotl_sunset"
- These are almost completely empty and are neither emitted nor rendered; they merely serve as parent particles for the aforementioned "sun" particles

It appears that by assigning Morning Glory and Death at Dusk as children to empty parent particles, all the weirdness regarding their spawn positions is averted.
This simple fix takes minutes to implement, and could solve a problem that has been pestering players for years.
