What's new:

• cannon tower now changes its appearance up to 5 level
• cannon rotation speed now increases every level for 0.5 and fire rate decreases for 0.1 (cap is 0.5 sec - that means that the cannon cannot shoot faster that 1 time per 0.5 sec)
• now the confirmation board on the table will be attach to table so when you teleport anywhere with it the confirmation will stay on the table
• adjusted the postion of the flaming tower icon on the table so it was visible

Fixes:

• fixed that arrowed tower matertial was wrong on the table when upgrading to lvl 3-4
• fixed too high values of towers health when upgrading already existed items (Newly spawned towers had correct values)
