Populate rules for the Spell-Slinger

[ChaelCodes]

Describe the Feature

The Spell-Slinger Playbook exists, but there are no moves, improvements, nor gear populated. This makes it rather hard to play as the Spell-Slinger.
We have seedfiles in HK that will load data into the database upon deployment and creation. These files should be idempotent and would help us load rules governing the spell-slinger into the database.

Describe the Solution

Solution
Add the Spell-Slinger improvements, moves, and gear to db/seeds/playbooks/spell_slinger.seeds.
utilize an example from the Chosen seedfile.
The Spell-Slinger Rules can be found at https://www.evilhat.com/home/wp-content/uploads/2019/03/Monster-of-the-Week-Revised-Playbooks.pdf
The seedfile will be automatically run in production upon merging. You can test it locally by running bundle exec rake db:seed:playbooks:spell_slinger.

Moves

If the move is rollable and has a result, the type is Moves::Rollable and the results are broken between six_and_under, seven_to_nine, and ten_plus. Don't forget to add the rating for the roll!
If the move is flavor text, modifies a roll, or does not result in a roll, the type is Moves::Descriptive.

Gear

Gear has 6 attributes: name, description, harm, armor, playbook_id, and tag_list. The playbook_id should always be @spell_slinger.id. name is the name of the weapon, description is optional. If playbook_id is included in the find_or_create_by, then it does not need to be in the hash of attributes. tag_list should be an array of strings. The easiest way to supply that is the following syntax: %w[close reload small]

Improvements

Several different types of Improvements need to be loaded. Here is a series of examples of how to translate common improvements to a model.

Description	Type	Attributes	Notes
Get +1 Sharp, max +3	Improvements::RatingBoost	stat_limit: 3, rating: :sharp
Get +1 Tough, max +2	Improvements::RatingBoost	stat_limit: 2, rating: :tough
Take another Spell-Slinger move	Improvements::PlaybookMove	stat_limit: 0	If there is more than 1 Take another playbook move, add a stat_limit with a negative number. This will make unique PlaybookMoves, so they aren't overwritten or deduped.
Take another Spell-Slinger move	Improvements::PlaybookMove	stat_limit: -1
Gain an ally: one of your old crew.			NOT IMPLEMENTED See #94
Recover a stash of money from the old days, enough to live without care... for a year or two.			NOT IMPLEMENTED
Take a move from another playbook	Improvements::AnotherMove	stat_limit: 0	See Improvements::PlaybookMove for notes on uniqueness
Take a move from another playbook	Improvements::AnotherMove	stat_limit: 0

Advanced Improvements

All advanced improvements have the attribute advanced: true, so they can't be added until you have 5 improvements.
