Created character_lookup table for applications that mirrors all character_ table fields minus blob fields for application lookups

Browse Source 
- A 2.4GB character_ table will take 7 seconds to query on a SSD versus .1s on the character_lookup table
	- This also causes applications like Magelo to burst reads of the entire character table because of the blob fields that come with the reads, as much as 500-600MB/s even if a indexed id filter is provided
	- This field is synchronized on player save and has 0.001s DB hit
	- When we split out from the blob, ideally this table can be removed, but it really does no harm in mirroring data when a 2.6GB character table mirrors everything subtracting blob data down to 8MB
	- Required SQL: utils\sql\git\required\2014_08_24_character_lookup.sql
