Sword improvements/tweaks

[Vindicatør]

There are not much players that use their weapons to fight off the troops, unless it’s early-game, so here are my ideas on how to change swords in Tower Defense:

Swords
Sword 1(I): Is a wooden sword, deals 8 HP(4 Hearts), 4% chance to deal knockback to troops, abilities last for 2 seconds

Sword 2(II): Is a golden sword, deals 10 HP(5 hearts), 5% chance to deal knockback to troops, abilities last for 3 seconds

Sword 3(III): Is a stone sword, deals 15 HP(7.5 hearts), 7.5% chance to deal knockback to troops, abilities last for 5 seconds

Sword 4(IV): Is an iron sword, deals 22 HP(11 hearts), 10% chance to deal knockback to troops, abilities last for 7 seconds

Sword 5(V): Is a diamond sword, deals 30 HP(15 hearts), 12.5% chance to deal knockback to troops, abilities last for 10 seconds

NONE OF THESE KNOCKBACK CHANGES WILL APPLY TO GIANTS, SLIMES, OR WITHERS
