v.17.8: yet another balance pass

• Added: little ui icons for aero & strikers weapons
• Balance: reworked nyctalus, faster set up, better range, weaker AtA missile, stronger landed weapon & switched weapon sprite to reduce confusion pteropus for now
• Balance: nerfed hp of all walls above rustyIron, as they scale too high per tier
• Balance: repair pin now can accept coolant, coolant allows it to fire faster
• BugFix: Construct Cheat menu Multiplayer fix
• BugFix: luridiblatta's database entry no longer shows the area damage as a frag bullet
