Misc 1.7beta5

Meaningful patch notes in approximate order of relevance:  
  
- Tweak difficulty settings for nightmare (rare spawn rate increased from 6.77%->12.5%, zone level multiplier decreased from 50%->25%)  
- Buff the celestial/radiance tree  
- Give all melee classes that don't currently start with a point in weapon mastery at birth a point in weapon mastery at birth; this also serves to make sure randbosses have the weapon mastery they need  
- Improve Pace Yourself  
- Slightly increase dammod for knives (45% str/45% dex -> 50% str/50% dex)  
- Slightly buff glyphs by making them no longer prioritize yourself before enemies for placement   
- Buff Dawn's Blade  
- Make Vor Pride's special vault have a slightly friendlier layout  
- Remove digging from all vaults that currently require digging  
- Add a fun mechanic to prevent farming of ruined dungeon orbs to get alchemy ingredients  

Mostly irrelevant other changes:  
  
- Make orc summoners and orc grand summoners use psiblades instead of slings, give skeleton assassins resolvers.sustains_at_birth, reduce how many turns mind parasite puts talents on cooldown for, remove object cost multiplier from slazish fens, make stoning poison no_npc_use

Fix d'old bug d'adept

The Adept prodigy in 1.6 was known to give an additional 0.3 mastery in some cases, often when the player got an escort tree. 
Now the effect of Adept has been changed, but this bug still remains and can be triggered, when you get bonus mastery over a tree whose category type you have a bonus mastery on, though these cases are much less likely to happen now. Currently there're 3 items giving bonus mastery to category types: Ring of the Warmaster giving bonus to Techniques, Rope Belt of Thaloren giving bonus to Wild-gifts if the wearer is a Thalore, and Radiance giving bonus to Celestials. 
Examples of cases that can trigger this bug: 
1) You don't have Conditioning tree and have saved a warrior escort with the Ring of the Warmaster on. Then you'll get the Conditioning tree at 1.60 mastery. 
2) You, a Thaloren Oozemancer who already unlocked Fungus tree with a category point, went to Zigur to complete the antimagic trial and then killed the High Tempest and came back to Zigur again to claim the rewards, with Rope Belt of Thaloren on all the time, will have both Antimagic and Fungus trees at 1.80 mastery. You get the 0.20 bonus mastery to Wild-gifts twice when the quests increase the masteries of the 2 trees. 
You can even unequip these items later, and the "free" bonus you get won't dissappear.
