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
