Patch 197: Bussard Ramjet and Miscellaneous [beta]

Added the Bussard ramjet which generates a large amount of energy when your ship is inside a space nebula. Together with batteries, this can be quite useful. Let me know your thoughts regarding the balancing! :) - Adjusted the nebula spawning mechanism to make sure that nebulae spawn in most sectors. - Placing modules in front of weapons is no longer forbidden. The weapons will show a warning but you can ignore it. This enhances what you can do with joints and pistons. - Reduced the number of ships which can spawn in the von Neumann missions from 10 to 5. Also, the search range in the ship selection algorithm now expands way faster. These changes should reduce the slowdowns/freezes encountered by some players. To keep the difficulty sort of constant, two extra waves are added. - Shots fired by the missile launcher array no longer spread as strongly to the side. - Addressed freezes related to large previous log files.
