Unity 5.2

Hot on the heels of 5.1! Thanks to Tim for corrections and clarifications throughout.
The major things:
- New Archery martial style.
- More of the mage's dedication to the south revealed.
- priestly synergies now cost 1XP each, with no increase in cost.

Additional, minor changes:
- Formatting updates, pre-reqs should now work the way you think they work.
- Eternal foe now costs 1XP (down from 2XP) (in the Cultist section).
- Responsive action clarification (in the priestly Healing section).
- Domain of protection clarifications.
- The mage dedications are now fully in alphabetical order.
- Silence now can be ended by losing half your mana, rather than all of it (in the Magic->Void section).
- Additional powder clarification (in the Trinkets section).
- You can now pause learning a lore to learn a different one.
- More enchanting clarifications (clearly I was not in a coherent state when I wrote that bit the first time :P).

Updates to the rules will not usually be this often, this should be it for at least a term.
