Prompt for finalName when creating project, or default to project name

Currently forge does not set the finalName of the project. In a WAR project, it's common to exclude the version from the generated war, which is done by setting the finalName as follows:

<build>
    <finalName>${project.artifactId}</finalName>
</build>

This should either be the default in forge, or forge should prompt the user for a name when switching to a war project (informing them that this name will be the name of the generated war).
