--- balance / mechanics

- changed the way energy drain from weapons is factored into the unit costs
(some of the cheaper energy-intensive units are slightly more expensive, others with energy intensive beams are a bit cheaper)

- units with high spike damage are now slightly more expensive (up to about 10% in general, with 20% more on AVEN and GEAR level 2 bombers)

- very long range plasma cannons and railgun energy drain raised from about 200 to 300 E/s

- increased cost of AVEN's disruptor units by about 25%

- paralyze damage scales up to +200% based on target's missing HP percentage, up from +100%

- fixed an exploit where upgrades could stack after giving units to other player with different types of upgrades

- fixed collision volume size and position for some units and many buildings (some were slightly floating above ground)

- fixed dynamic collision size adjustment and aim position for pop-up defense turrets

- teams are automatically marked as defeated if they have less than about 4% (8% for AI) of the strongest team's strength
(this means players can now end the game without having to search and kill EVERY enemy unit, as some may be hard to reach)

- Air Repair Pads have been removed (they may be added with new mechanics on a later date)

- dragons teeth and fortification walls can now be built underwater

--- effects / visuals

- fix magnetar effect being visible while it's still under construction
- show green glow effect and particles when morphing commanders
- improved CLAW "Grinder" Form's weapon model
- added unique wreckage models for all commanders

--- UI / widgets

- fixed an issue where upgrade status for enemy units would not be shown on the tooltip
- added widget that sets some bombers to HOLD FIRE when built (regardless of the plant's fire state)
- added a custom taskbar icon
- player list changes
. merged resource bars and information for allies into the player list on the bottom right
. shows relative resource income % for all players : highest known income shown as 100%
. shows TrueSkill value when available instead of rank

- show circles under selected units instead of the default selection squares (based on widget by Trepan)

--- AI

- fixed "easy mode" MFAI wasting much more time than intended (difficulty is slighly increased)
- "onslaught mode" MFAI resource income bonus grows by 2M/s and 20E/s with every passing minute
- "onslaught mode" MFAI resource income bonus no longer grows with estimated team disadvantage
- CLAW and SPHERE AI may build anti-sub L2 aircraft (their air squad's no longer completely helpless against underwater targets)

--- other

- changed recommended springRTS engine version from 100.0 to 103.0
