Feature: Loot system enhancements

[vwalsh]

• Number type config input should allow selecting a value from loot, validate it's a number within the min and max range set and then use it's value in the command
• Select type config input should allow selecting a value from loot, validate and use the value within the command
• String type config input currently allows for the loot variable to be pasted in as it's value, validation is still required to ensure the value is acceptable to the input. this would require looking up the loot value if a VALUE is supplied or if it doesn't match that pattern then validating the given input
