Move coleslaw-conf to its own ASDF system

Ideally the package coleslaw would only have symbols that refer to
configuration variables. However to ease setting *BASEDIR* to the right
value using UIOP:SYMBOL-CALL we provide a setter, SET-BASEDIR.

- Split each ASDF system into its own file

- All system definitions are made in the ASDF-USER package, as
recommended by ASDF.

Fixes #110
