v0.2.0: start using Go modules (#67)

Now with Go modules.

The v0.1.4 introduced the backward-incompatible change.
It was intended to be a minor version bump, but oh well.

Multi rule sets support

• -rules now support multiple rule files (comma separated list)
• ruleguard package exports a function for rule sets merging

Wide suggestions fix

• Fixed #57

Minor improvements release

• dsl/fluent dependency is embedded into the ruleguard (#23)
• Source text is used for the interpolation (#11)

First open release

This version includes basic functionality and is considered to be good enough for trying it out.

Upcoming releases are going to address any issues found during this one.
