Balancing

• Changed expensive variant of electronic circuit to require 8 copper cables instead of 10.

Modding

• Changed how beams are drawn to improve seamless tiling of beam segments. Head and tail segments are now stretched to fill space from source/target position to next segment.
• Changed how beams apply damage. By default, they no longer trigger their action every damage_interval, instead the action is triggered when its owner triggers shooting. The old behavior can be turned on by setting BeamPrototype::action_triggered_automatically to true.
• It is possible to specify fluid product or ingredient with a fluidbox_index so they use exactly one slot corresponding to the specified fluidbox of the machine.
• Changed the "market" entity from entity-with-health to entity-with-owner so it now has a force and unit_number.
• Changed fluid energy source prototypes to error when no consumption limits are set instead of logging a warning.
• Added util.parse_energy().
