Movement choices and token avoidance

New features

• Add setting for pathfinder to avoid all tokens or hostile tokens. Closes issue #37.
• Add selector to Token HUD to choose between walk/fly/burrow movement types. Default is to automatically choose based on elevation. Closes issue #33.
• Add getter Token.prototype.lastMoveDistance that tracks the last token move. If combat is active, this returns 0 if the token has not yet moved this round. Use Token.prototype._lastMoveDistance to find the actual last distance moved regardless of combat.
• Add setting to round ruler measurements, for use with gridless scenes. Thanks @Larkinabout for the PR!

Bug fixes and other improvements

• Misc. fixes to pathfinding to reduce likelihood of it failing to find a path or finding an incorrect path.
• Fix for waypoint elevations not finite. Closes issue #38.
• Refactor of elevation handling to account for Token Ruler tokens versus primary ruler.
• Move settings related to speed properties to CONFIG.elevationruler.SPEED.
