Add more weapons for Invisible Blade

[Dreams]

This class is very niche and extremely limiting when it comes to considering what can actually function on Arelith whilst taking advantage of the class abilities. Expanding the weapon selection can help this:
- Make IB weapons all Small or Tiny One-handed Edge weapons.

Light-pick/Handaxe: Gives DEX-based characters who are not heavy rogue some ability to deal damage.
Kama: Monk options (I'm unsure if the stacks are limited to per hit or per round. If the latter, this isn't a problem, if the former then perhaps consider this further).
Sickle: This is an uncommon weapon as it is and easily fits the idea of an Invisible Blade turning an unlikely weapon into something deadly.
Sai/Wakizashi: Very little difference between daggers/shortswords and sai/wakizashi when it comes to mechanics. This opens up other styles and aesthetics.
