PTDE SFX Merged

Prepare to Die Edition SFX and Some PTDE Common Effects conflict and overwrite each other and you lose out on the SFX effects of PTDE SFX and the fixes that come with Some PTDE Common Effects. So I went ahead and merged them and did some patchwork on a couple known problems with the mod. Projectile SFX for arrows and bolts have been partially fixed as I reverted them back to Remastered style (you can barely notice the difference) but certain bolt types still have purple textures. I reverted the Undead Dragon toxic breath back to Remastered style since Prepare to Die Edition SFX had a bug that rendered it invisible.

Outside of that, the problems that weren't fixed in these mods still remain: Hellkite Dragon fire still invisible on the bridge and many effects are still slightly too bright for Remastered and need tweaked. Don't forget to endorse the original mods.
