errai-cdi-async-databinding-tests not working on Windows and untracked files in errai-aerogear-demo

Hi Errai team,

When cloning the project for the first time and performing a mvn install on the parent I found two minor issues.

First the errai-cdi-async-databinding-tests were not able to run because the pom.xml contains a line break in the <argLine> that is defined for the forked java process. This causes problems at least on my Win 7 machine. By removing the line break i could fix this issue.

Additionally when building the errai-aerogear-demo project i could see that some file were generated under the /src/main/webapp directory. Because the project does not contain an git-ignore file these auto generated files show up as untracked files. I created an .gitignore file that improves that.

Hope that helps.

Cheers Gert
