#85 - Formalization of artifact publishing and releasing policy - step 1

[gslowikowski]

These are very small changes to scalac-scoverage-plugin build:

• version changed from 1.0.4 to 1.0.5-SNAPSHOT,
• snapshot publishing to Sonatype snapshot repository (not local Maven repository).

[gslowikowski]

Proposed changes are:

1. master branch should have next version snapshot in build file, so everybody could build it and test locally without any changes: sbt +publishLocal to publish to local Ivy repository (for SBT) or sbt +publish-m2 to publish to local Maven repository (for Maven), I don't know which repository is used by Gradle, anyway one of these two
2. Sonatype snapshot repository should be defined in publishTo for snapshots, not lical Maven repository. For publishing to local Maven repository use publish-m2 task. After each change (if the author feels it's stable) new snapshot should be published (sbt publish). This way SBT, Gradle and Maven plugins developers will have to do nothing to use latest version of scalac-scoverage-plugin in their plugins. No need to install it locally before, just depend on a snapshot.
