fixed: replacing one square of a higher tier 2x1 armor piece with something else the other square should be armor of the same tier as the 2x1 piece (was just basic armor up to now)
added 1x2 Armor Wedge and 1x3 Armor Wedge
added functionality to Armor that when, destroyed it gets replaced by structure - as all other armor pieces had this

added missing entry for the control editing menu which was causing the game to crash on trying to change hotkeys

Engine Room Mk4 copy-replace error on doodads_high fixed

added tiered versions of the arc shields (changed the names as well to better distinguish them)
large shields (now called large arc shields) no longer get blocked by other parts
arc shields also got changed to provide better penetration resistance at low energy levels (from 0 at 1 energy to 50% of maximum)
moved some tier icons to make them (barely) visible in blueprint mode

Moved the icons a bit so they are as visible as possible in blueprint mode - unfortunately, especially on smaller parts, the blueprint still occludes the icon.
Also, fixed Engine Room Mk5 resource cost - those sales on parts WILL end!!

added missing stats to the factories for the new resources - unfortunately i can't order the stats to be in the same order as they are on the vanilla factories

small spherical shield was missing both tier toggles

final version of the tier icons
added a toggle to navigation mode to show/hide the icons on all parts at once with hotkey (ctrl + t)

also modified how many of the new resources pile up on the stations

added tier icons to all parts

last beta of the tier icons
