more changes

- Changed the data types to blob(16)
Added async conversion

- Added method to convert asynchronously. I don't think it's working,
when opening the sqlite database I see
"javax.sql.rowset.serial.SerialBlob@4ac6ee33" in the ownerid column
- Also, it appears you cannot at the moment get the UUID of a player
which has never logged on your server... I guess the uuid is saved in
the player dat file.
Conversion finished

- Finished the conversion, seems to work. Haven't tested if the saved
values were correct. Used evilmidget38's class.
- Still need to test to rest.
Might fix

Might fix being unsable to use stuff, like horses, carts...
Fix to names

- Now ignores case
