Log calls don't check if the respective logging level is enabled

[fabiangebert]

Thanks for this great plug-in. I'd like to suggest a performance improvement: currently, there are tons of "log.debug" calls that obviously don't have an effect but will result in expensive computation (if you process a lot of data).
Why don't you prefix every line with

!log.debugEnabled ?: log.debug...

or more explicit

if(log.debugEnabled) log.debug...
