makes things that are IS_SHARP_ACCURATE sharpenable, as well as things that are just IS_SHARP
makes sharpness not change unless it's a super-sharpening block
sharpening blocks can now only sharpen items that are already sharp, like knives, axes, etc. (super sharpening blocks don't care though)
max damage from sharpening is now 30 (no esword/ninja sword sharpening), increment is still 4 though
!!items can only be sharpened once!!
twohanded items (fire axes, spears) have their force when wielded increased rather than normal force increasing
double prefixes are no more. instead, it now goes sharpened, twice-sharpened, and thrice-sharpened. there should never be an item that is sharpened more than three times, which works out because there is no word that comes after thrice (thank you so much @razharas for the code for this)
a little bit of weirdness got stuck on the sprite when i first implemented it due to a goof when i removed the transparency, it is now fixed
sharpening now gives a message to bystanders telling what you sharpened
items with any block chance of any kind cannot be sharpened. separation between shields and weapons is absolute.
dull sharpening block -> worn out sharpening block
increments in force/throwforce now use Clamp()
adderol -> adderall
might be some other changes that i forgot but this is really the important stuff
