Make settings character-specific

[DarthKsane]

Hi!
It would be wonderful to have different currency lists per character.
I found two ways of making this.

1. Easiest. In Scoreboard.toc change "SavedVariables: ScoreboardSettings" to "SavedVariablesPerCharacter: ScoreboardSettings".
   After that all settings would be saved in "WTF\Account\ACCOUNTNAME\RealmName\CharacterName\SavedVariables". And that's it.
2. Complicated but flexible. Make character-specific settings support inside addon manually.
   I started to code this and make function getDB (for nice looking and future adding character name inside getDB and setDB) DarthKsane@6cbe585
   but then suddenly found out about 1st way.
