Spells: Mage Bolt Line

[finalgrunt]

- Indeed, without a target or targetting yourself, bolts would flight straight ahead, but I don't remember it was aggroing anything crossing the line of shoot (I remember trying over and over to get it to hit something in orc highway).

- Landscape but not the players would "destroy" the bolt on hit.

- Bolts were a tiny bit faster than what their current speed is.

- Bolts for magicians at least looked like a fire (for the color) flare.
