Added support for remnant effect

[greatnameincoming]

Description of the problem being solved:

Adds support for

• Remnants have #% increased effect
• Effect and duration of chayula flames on you is doubled (legacy mod). The duration part of this line is ignored.

This has been applied to work on:

• Into the breach flames (from chayula monk)
• Life remnants (from bloodmage)
• Mana remnants

Only the purple breach flames are actually used in calculation, the others only show up in the Calcs tab.

Steps taken to verify a working solution:

• Verified remnant effect correctly scales the values of the above skills in the Calcs tab
• Verified the remnant effect modifier and breakdown is correct
• Verified the chaos damage applied by purple chayula flames is correct
