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)
