remove start altar

Up version number

Add cost handler, preventing people from buying enchantments that are too expensive

Add enchantment descriptions to the altar buttons on hover.

- Fix modular causing enemies to spawn double gold
- Fix modular not working in some cases (i think)

- Altar price is now individual for each button within the altar.
- Price scales with the amount of enchantments and their levels.
- Max enchantment level and count per button scales with a internal "skill" value, the more spells you have enchanted in the run, the higher level enchantments you can get and the more enchantments per button you can get.
- The too many enchantments error now takes into account if the spell already has that enchantment, so that you can still increase the level of a enchantment on a spell if your spell has 4 unique enchantments
- Every altar now has a unique set of enchantments for the same spell card.

Scale enchantment levels, count, and some other stuff with the amount of times you have enchanted spells. This should improve balance a bit.

Fix flappy spells

fix price being invisible

Fix the mod making some spell names empty. Might also improve compatibility with other mods.
