untagged-e134e4c9d864272e63c6: Add new modifier action called string

This accepts a variable name followed by a space and a string value to set the variable to.

untagged-6fd020274b8ba19882e0: Added instant.VariableCastSpell

This spell is designed to cast a spell based upon an internal spell name contained by a string variable.
There is a required option on the spell called variable-name which accepts a string matching the name of the variable to read from for determining what spell to cast.
There is another option which may be specified on the VariableCastSpell called str-doesnt-contain-spell. This option specifies the message to display to the caster if their variable does not contain the internal spell name of a valid spell.

Create data structure, VariableDouble.
This will aid in making spell fields more flexible and dynamic.

untagged-1b3836e4bc4644270987: Added additional meta variables.

These meta variables will only be accessible in versions of spigot where
the class org.bukkit.attribute.Attribute exists and that class defines the relavent attribute type.
These attribute focused meta variables modify the base attribute stat of the subject, meaning it is applied before things like potions, armor, etc.

The new meta variable names are
- meta_attribute_generic_armor_base
- meta_attribute_generic_armor_toughness_base
- meta_attribute_generic_attack_speed_base
- meta_attribute_generic_knockback_resistance_base
- meta_attribute_generic_luck_base
- meta_attribute_generic_max_health_base

Added additional utilities to CompatBasics.
