Sneak Attack Perk Tweaks

After investigating and experimenting a bit, I came up with this.  The descriptions are a little ambiguous on how the effects of Cloak & Dagger, Mister Sandman, and Ninja should be stacked, at least in regards to ranged sneak attack bonus with a silenced weapon (some of the perks have other effects that don't stack) - should the bonuses all apply to the base sneak attack multiplier (2. 0x) or multiply by each other (or somewhere in between)?  Thus I decided to make a mod with multiple variants and see which ones are more popular.  I'm guessing "hardcore" players will go for the low multipliers, and others will go for the high multipliers, and the in-between ones will get few downloads, but I'll find out.

Also, with regard to Mister Sandman, I noticed that the "Sandman Kill" prompt showed up when I was close enough to a sleeping NPC, even if I was in a friendly area. (and so I had my weapon holstered etc.)  All variants of the mod include extra conditions, so this prompt will only show up if you're sneaking and have a weapon drawn.  Another thing I've noticed is that with just Mister Sandman up to rank 3 (and no other perks), the sneak attack multiplier is 2. 5x, even though the description says "Your silenced weapons now do 50% more sneak attack damage."  That 2. 5x could be considered as adding 50% of base damage to the sneak attack, otherwise to match the description it should really be 3x.

All variants use ESL-flagged ESP files, so they won't take up an ESP slot in your mod order.

Anticipated Questions

Q: Why not make an All-in-One FOMOD installer?

A: I probably will eventually, but that would not tell me which options are more popular - if some of them are sufficiently unpopular, I may drop support for them in future versions of the mod.  One option turned out to be more than 4 times as popular as all the others combined, based on "Unique DLs", so I see little point in doing this.

Q: What about the existing mods "Ninja fix" and "Mister Sandman Unfixed"?

A: I'm aware of them, but based on their descriptions, they handle things differently and only give you one choice of how to "fix" the issue, and they assume that it was caused by mixing addition and multiplication, apparently not realizing that this can be made consistent just by making sure the entry points involved all have different priorities.

Q: What about the Unofficial Fallout 4 Patch?

A: Last I checked, that didn't completely fix the inconsistency - see https://afktrack.afkmods.com/index.php?a=issues&i=31307 and if/when it does, it will probably stick to one final multiplier, rather than giving players choices.  However, if the UFO4P devs look at the download counts of the this mod's variants to decide what multiplier to go with, I won't object.  Also, this mod includes UFO4P's fixes to melee coverage by the Ninja perk, and a small change to the priority to allow the Ninja pe
