[#342] Apply senses/movement to actor when race is added

[arbron]

• Movement types and senses are applied automatically, assuming the current value on the actor isn't already higher
• Creature type isn't applied yet because we don't have it displayed on the actor, I'll handle that in another PR
• When deleting the race, movement and senses are unapplied if the value is equal to that on the race (so we don't get rid of values if the player has changed them)
• We now prompt when removing backgrounds & races with advancement just like with classes & subclasses
• If the player unchecks "Remove advancement changes" when deleting a race, it will not unapply any of the direct changes

@Fyorl Since creature type on PCs has been merged, I've added support for that into this PR.
