Some break changes in Ktorm 3.0:

• Completely remove the deprecated global database APIs and provide equivalent things in a new module ktorm-global.
• Use = instead of property delegation to define columns.
• Query doesn't implement Iterable anymore.
• Support compound primary keys.

In addition to the break changes above, there are also many updates from enthusiasts in the open source community, thanks for their contributions:

• PostgreSQL hstore data type and a series of operators for it. Thank @arustleund
• ktorm-jackson supports simple Jackson annotations, like @JsonProperty, @JsonAlias, @JsonIgnore. Thank @onXoot
