0.5.3 Bugfixes

Publishing some fixes to errors I noticed in development and play after the big 0.5 launch.
- Vehicle spaces changed to 30 from 25, since vehicles theoretically use 3AP to move every round. 
- Blocking roll added (Dexterity, against attack number), since other features were giving advantage/disadvantage to an action without a roll. 
- Character speed changed from 5+Agility to just Agility, and running changed to x5 speed. 
- New movement action "sprint" added, taking 3 AP to gain x10 speed, but at the cost of the Exhaustion status effect. 
- Basic info for angle added (I need to add a lot more for this later) 
- Species and feature examples updated for balance, especially around the Intelligence and Agility stats. 
- A few other small typo corrections and clarifications, as well as small tweaks for streamlining and simplification. 
Currently, I'm working on a few big changes to streamline spells and make them a bit more like weapons, but that isn't included in this update, since I wanted to push out the bugfixes early (so the magic features and spells pages at the end are not formatted quite correctly).
