v0.5.0

This version contains a lot of breaking changes. The nessie.config.ts and migration files are all changed, so when using this version, you will have to update all nessie files. The whole folder structure is also entirely changed, so to import the query builder you need to get it from qb.ts. The clients can be found in mod.ts, and the CLI is still in cli.ts. A new option is now available for migrate and rollback, namely amount. You can now pass a number, all or leave it empty to decide how many files to handle (see readme for more information).
