Plugins not works with surreal DB

[josselinchevalay]

Hello,

i remark your plugins cannot works with new version of surreal 2.0

Header change :

NS => surreal-ns
DB => surreal-db

@josselinchevalay thx for pointing that out, I would propose we introduce a either a config option or a automatic detection of the current running Surreal DB to overcome this issue.
