Add "same" mouse button options

[Nixill]

Full suggestion: Add "Replace same thing", "Replace same type", "Replace same weapon material", and "Replace same weapon type" to left mouse (the latter two only showing up when you're placing a weapon), and add "Delete same thing", "Delete same type", "Delete exact same thing", "Delete same weapon material", and "Delete same weapon type" to right mouse (the latter two only showing up when you're placing a weapon).

"Same thing" will replace / erase anything that is the same thing as the selection (e.g. if a blue slime is selected, all blue slimes will be replaced / erased under the cursor, but no other existing enemies or objects will; unoccupied spaces will be unaffected)

"Same type" will replace / erase anything that shows up in the same tab (e.g. if a blue slime is selected, any enemies will be replaced / erased under the cursor, but no other existing objects will; unoccupied spaces will be affected)

"Delete exact same thing" will erase anything that is the same type and same properties as what's selected in the panel on the left (e.g. if a non-lord blue slime with 0 beat delay is selected, blue slimes with 1 beat delay will not be erased, nor will lord blue slimes). This isn't suggested for replace because it'd do literally nothing.

"Same weapon material" will replace / erase any weapon that is the same material as the selection (all weapons that don't have a material - the Blunderbuss; Daggers of Frost, Jewels, or Phasing; Glass Shard; Flower; Golden Lute; and Rifle - would be considered to be the same material as each other, but not the same as any other material).

"Same weapon type" will replace / erase any weapon that is the same type as the selection (all weapons that don't have a multi-material type - the Blunderbuss; Glass Shard; Flower; Golden Lute; and Rifle - would be considered to be the same type as each other, but not the same as any other type).
