Hot reload CSS/LESS stylesheets during gwt:codeserver

When running an application with

gwt:codeserver

Errai generates intermediate classes to be compiled by GWT, I'm particularly refering to the fragment generated at :

org.jboss.errai.ui.rebind.TemplateCodeDecorator#generateTemplatedInitialization:258

It compiles the stylesheet into a string that will appear inside the intermediate class, which in turn will be passed to the StyleInjector at runtime.

It would be really great if these stylesheets could be recompiled/reloaded during development, now the only option I have found to reload styles is to delete the gwt target directory and restart the codeserver, which is really time consuming when you want to adjust styles during development.

P.S. I recently started using Errai and I want to say it is really awesome, keep up the good work !
