add deployment on TomEE

working
- deployment and execution on TomEE `mvn tomee:run`

known issues
- the context root is `/Foodeys-1.0-SNAPSHOT` instead of `/Foodeys`, using option `<finalName>${project.artifactId}</finalName>` in the pom.xml would solve it, but this collides with the deployment option `<contextRoot>` of embedded glassfish, which then would not work
- the autocomplete function isn't working on the page, even the REST service seems to be functional, calling the URL `http://localhost:8080/Foodeys-1.0-SNAPSHOT/rest/search/autocomplete/` returns a JSON response
