Update documentation or release new version

[eximius313]

In README you write:
add the dependency in your build.sbt file: "com.actimust"% "play-spring-loader" % "1.0.0-SNAPSHOT"
while should be:
add the dependency in your build.sbt file: "com.actimust"% "play-spring-loader" % "1.0.0"

because

or please release version 1.0.1 because it seems that in 1.0.0 this PR #6 is not merged, because I got:
