Git: Document the easy import feature

Document this use case: As a Java EE developer, in some cases using Git for the first time (or only familiar with command line git), I find it very difficult to clone and import a project correctly into JBDS, having the appropriate facets configured, if it has a maven pom.xml, correctly setting the build path, where it is easily deployable to a localhost EAP instance.
The mission here is to make the Git experience much more user friendly.
