source generation task changes Logback configuration and doesn't change it back

[ghost]

In ScalatePlugin.generateScalateSource, you're doing this--

System.setProperty("logback.configurationFile", logConfig.toString)

-- where, by default, logConfig is the current project directory plus "src/main/resources/logback.xml". However, the property never gets cleared after the task runs.

The result is that if you also have a logback-test.xml, which Logback is supposed to use preferentially, it'll be ignored and you'll waste some time wondering why it keeps insisting on using your production logging settings in a development environment. My workaround has been to add a hook to the compile task (compile andFinally { System.clearProperty("logback.configurationFile"); }), and I guess I could also calculate the absolute path to my logback-test.xml file and set scalateLoggingConfig to that, but I don't think either should be necessary -- the task is just not behaving well here.

It would be awesome if you all could release a new version so that we could start using this fix. :)
