Changes for BETA round 22

Brand new year, brand new round. New is always better! We have some changes and bug fixes. On the menu:

• Push messaging for Android & Chrome users integrated
  Can be activated and deactivated right here. Also added a bell icon in the menu. Will send you a push notification upon being attacked, research completed or a new message received. Unfortunately, iOS users will have to wait a bit longer for the same integration. Because currently, I have no idea how to build it, but will try to solve.
• Resume war function added in again
• Siege chopper life decreased from 50 to 45
• Harrier life increased from 45 to 50
• Harrier attack power increased from 45 to 50
• Rocketeer attack power increased from 35 to 40
• Battleship attack power increased from 110 to 120
• 50% damage reduction for buildings when target under 10.000m2 land also added for missiles and satellites.
• Sliding scale implemented for building damage reduction 
  When at 5.000m2 land or below, you will receive the full 50% damage reduction. Up from 5.000m2, the damage reduction will scale.
  e.g 40% damage reduction at 6.000m2 land, 30% damage reduction at 7.000m2 land, 20% damage reduction at 8.000m2 land, 10% damage reduction at 9.000m2 land.
• Small display bug fixed and tweaks
