Converts hard-coded variables to datums in the fishing subsystem + minor fishing skills cleanup

[Gboster-0]

About The Pull Request

• Recodes the fishing subsystem to have a list of datums instead of hard-coded variables
• Fish market now checks for the map before the proc, so admins can easily enable the CF/COL fish markets at their demand (let me test things locally easier dammit!)
• Fixed a lot of fish bugs

Why It's Good For The Game

Recodes the fishing subsystem to have a list of datums instead of hard-coded variables

• The shitcode and hardcode is real, cleaned it up a good chunk
• This does also allow admins to make custom planets, or copies of pre-existing planets

Fish market now checks for the map before the proc, so admins can easily enable the CF/COL fish markets at their demand (let me test things locally easier dammit!)

• It just better, also i added a QDEL_LIST() before setting a new list there since quite sure those datums were never being cleared

Fixed a lot of fish bugs

• Bugs bad, the full list in the changelog
