Fix maven dependency declaration syntax.

See http://bugs.nextapp.com/mantis/view.php?id=521

If I try to use the echo3-filetransfer library within my maven project, the build breaks with this error:

Unable to resolve dependencies for assembly 'assemble-server': Failed to resolve dependencies for assembly: Unable to get dependency information for com.nextapp:echo3-filetransfer-webcontainer:jar:3.0.2: Invalid version for dependency com.nextapp:echo3-webcontainer:jar: Unbounded range: [3.0.0,

The problem is caused by this section within the dependency management:

 <dependencies>
        <dependency>
            <groupId>com.nextapp</groupId>
            <artifactId>echo3-webcontainer</artifactId>
            <version>[3.0.0,</version>
        </dependency>
...

The correct syntax of the version would be
            <version>[3.0.0,)</version>
