Ars Magica 2.5

This has been an absolutely huge update, a lot of things added and reworked. Among them:

• Five new spell components (3 of them new silver spells)
• New functionality to already-implemented spells
• Etherium gathering rework: You now have to use an extractor (item) on witchwood logs with a bucket in your inventory. This is optional and can be turned back to how it was (generating huge lakes) in the config.
• In-game documentation (I finally wrote everything I changed and added into the Compendium)
• Fishing in Nether lakes and the End void (can also be partially automated with flickers)
• Magical flowers (I promise it's more fun than it sounds!)
• Psychedelics (Does your magic mod them? No? Well now it's inferior)
• A whole mountain of bug fixes, too long to list.
• Some minor changes like balancing a few endgame recipes have also been made. Feedback and bug reports are appreciated.
