Added deprecation messages for incorrect capitalization in scripts

- These messages are temporary, only meant to help those with custom
  scripts to transition them to the correct case-sensitive syntax. If
  you ignore the deprecation messages you encounter, your scripts may
  continue to work just as they did until now, but this will no longer
  be true in the near future, and they may stop working at any time.

If you ignore this, and your scripts break, you'll get to keep the
pieces :)

Fixed item chain drop rate processing algorithm

- This corrects the absurdly high drop rate the Blacksmith skill Ore
  Discovery was granting, to its correct values (and processing
  algorithm) from Aegis.
- Special thanks to Ind.

Update rAthena-main-upgrade.sql

Now it deletes all entries on the sc_data table since it's dangerous if we port the sc data as is. WARNING, this ends all active SCs on the previous server! Even jailed state!
