Combined all of the basic stats modifier

[Crepestrom]

Fixes: #3611
increases maintainability of the code as you do not need to modify 8 basic stat modifiers in the same exact way
Breaks many addons that use the old system of modifiers
Also negative and positive modifiers are combined instead of being applied seperatly
eg: a +50% durability and -50% durability modifier will cancel out to +0% durability instead of -25% durability (75% of total durability)

Which is better

I almost like not seeing Fragile and Powerful and just having the stat change

[oridbot]

while I do definitely prefer no names, having names for the stat changes leave room for us to (if the player becomes familiar with those names enough) just state the names without the description. I would say it also gives the tool more of a reason for having these stats

alternatively you could do something like Powerful (+50% dmg) since i think the increases/decreases is kind of redundant when you have the +/-.

good point i will remove the increases and decreases
was also drawing away the eye from the number
