Regular Beta branch update

The following fixes are in beta on the beta branch

go to game properties/betas and select "beta patch".

this is a savegame safe update;)

• reduced war requirement to 400 population and an escort of 4
  
• depletion also returns a wood for level 1 towers and wood and stone for level 2(command) towers
  
• prevented a "we need stone to build here" message when clicking to fast"
  
• prevented players from building within a reasonable distance of another npc settlement (and thus claiming it conquered)
  
• prevented wonder placement message from repeating
  
• tradeposts don't show the text "depleted"
  
• inventory shows total unit cap
  
• bug prevented for infinite spawning capital ships if at max unit cap
  

let me know if any issues arise from these.
