replace sbt-release with sbt-ci-release

includes adopting sbt-dynver (to set `version`)
and sbt-travisci (to set `scalaVersion` and `crossScalaVersions`)

-### What's new?
-
-### 3.9.2
- - Use marker inside macros in is*Enabled methods
-
-### 3.9.0
- - Functions for on demand code execution added in Logger class
-
-#### 3.8.0
- - Added LoggerTakingImplicit, bugfixes.
-
-#### 3.7.2
- - Make logger to consume args of type `Any` with slf4 interpolator.
-
-#### 3.7.1
- - Remove @volatile from lazy logger, failing with strict compiler settings
-
-##### 3.7.0
- - Deconstruct Scala's string interpolation into SLF4J string interpolation.
- 
-##### 3.6.0 - flawed release
-
-##### 3.5.0
- - More Logger factory methods, bugfixes and upgrades, published for Scala 2.12.0-M5, 2.12.0-RC1, 2.12.0-RC2 and 2.12.0.
-
-##### 3.4.0
- - Fixes #38 - Logger.info() cannot be used with primitive types.
-
-##### 3.3.0
- - Fixes #42 - Request: Add Logger(class). README changes.
-
-##### 3.2.0
- - SLF4J loggers and our Logger now survive serialization. By survive serialization, we mean that the
-   deserialized logger instances are fully functional.

 ## String Interpolation
+
 It is idiomatic to use Scala's string interpolation `logger.error(s"log $value")` instead of SLF4J string interpolation `logger.error("log {}", value)`.
 However there are some tools (such as [Sentry](https://sentry.io)) that use the log message format as grouping key. Therefore they do not work well with
 Scala's string interpolation.
@@ -180,6 +145,7 @@ logger.error("my log message: {} {} {}", arg1, arg2, arg3)
 This has no effect on behavior and performace should be comparable (depends on the underlying logging library).
 
 ### Limitations
+
  - Works only when string interpolation is directly used inside the logging statement. That is when the log message is static (available at compile time).
  - Works only for the `logger.<level>(message)` and `logger.<level>(marker, message)` logging methods. It does not work if you want to log an exception and
  use string interpolation too (this is a limitation of the SLF4J API).
