Updates Scalameta Settings

[juanpedromoreno]

This PR changes the scalameta settings according to its tutorial, where it's using scalameta paradise 3.0.0-M10 together with scalameta 1.8.0 (instead of 2.0.0, it seems to be incompatible).

lazy val macroAnnotationSettings = Seq(
  addCompilerPlugin("org.scalameta" % "paradise" % "3.0.0-M10" cross CrossVersion.full),
  scalacOptions += "-Xplugin-require:macroparadise",
  scalacOptions in (Compile, console) ~= (_ filterNot (_ contains "paradise")) // macroparadise plugin doesn't work in repl yet.
)
// Requires scalaVersion 2.11.11 or 2.12.3
lazy val projectThatDefinesMacroAnnotations = project.settings(
  libraryDependencies += "org.scalameta" %% "scalameta" % "1.8.0" % Provided,
  macroAnnotationSettings
  // ... your other project settings
)
lazy val projectThatUsesMacroAnnotations = project.settings(
  macroAnnotationSettings,
  // ... your other project settings
)

Additionally, this PR:

• Upgrades joda-convert library.
• Bumps sbt-dependency version (including its settings in the defaultSettings).
• Disables sbt-coursier as a plugin enabled by default.
• Releases 0.7.2.
