Configurable area of effects for the following items:

Destruction Catalyst:
Explosive range, in tiles.
Centered [boolean] makes it so that the explosion is applied as if it originated where you clicked, instead of into whatever you're clicking.
Perfect Cube [boolean] makes it so that the farther you get from the origin, the higher a chance to not break the blocks.

Rending Gale
Radial push radius: The radius of the area around you that mobs will be pushed
Can push projectiles: Gives the push force the ability to throw back non-living entities that extend IProjectile

Glacial Staff
Snowball damage calculation separate from ice rod.

Harvest Rod
Bonemeal luck factor - a float (0 to 1.0), the rate of successfully gaining extra bonemeal. Numbers higher than 1 have no effect.
Bonemeal luck rolls - the number of times the bonemeal application rolls for bonus bonemeal usage. This has a multiplicative effect on the luck factor. Either can be set to zero for no luck rolls.
Harvest break radius - the range of the area-wide break effect on the harvest rod.

Sojourner Staff
Max range - cap it at 30, like it is now, just allow people to reduce the max.
Tiles per cost multiplier - defaults at 6, minimum of 6. (5 is default place range) let them set it to whatever, max is (max range) or 30, whichever is lower.

Rod of Lyssa
Use Leveled Success Rate - causes your player level to determine your chance of successfully stealing. Formula can't be modified. 1: (sqrt(level) * 2) of failure.
Config success rate - if not leveled rates, use this instead, (0.0 - 1.0) float determines probability of success on steal.
Always steal from an equipped slot - if this is false, the slot is randomly chosen, so there is no guarantee of success. If it is true, only an equipped slot will be attempted, meaning success can be guaranteed.
Anger on fail - causes 0 damage from player, causing the enemy to be angry at you. This can be disabled.

Twilight Cloak
Only works at night - means even if you're in the dark, it only works during the evenings.

Void Tear
On by default - When creating a void tear coded to an item,it auto-absorbs by default. This can be disabled.

Angelic Feather Jumping
The potency of the jumping effect applied by the angelic feather

Phoenix Down Jumping
The potency of the jumping effect applied by Phoenix Down

Lantern of Paranoia
Placement Radius - the radius in which it will scan for low light levels.
Perform visibility check - I may not be able to do this, but by default I would like it to do a visible block check for the player.

Ice Rod Damage
Damage - The damage a snowball deals
Fire Immune bonus - EXTRA damage a snowball deals to fire immune mobs
Blaze bonus - Extra damage a snowball deals to blazes, this is in addition to fire immune bonus, always.
(These will also be on the glacial staff)

Interdiction Torch Push Radius
Interdiction torch exceptions

I've added the commonproxy configs, now I need to implement them to each item.

Currently up to (and including) rending gale in terms of code completion.

These are done, i had to drop a few features that sucked, so not all of them made it in. Most of them though.
