Use Maven's managed dependencies

[tomasz]

Declaring the mvvmfx-* artifacts in mvvmfx-parent's managed dependencies gives users a centralised version management for all mvvmfx-parent descendants. It's extensively explained in Maven docs.

But simply speaking, it puts the required version of all mvvmfx-* artifacts in one place. Users now can declare dependencies:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>de.saxsys</groupId>
            <artifactId>mvvmfx-parent</artifactId>
            <version>1.4.0-SNAPSHOT</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>de.saxsys</groupId>
        <artifactId>mvvmfx</artifactId>
    </dependency>
    <dependency>
        <groupId>de.saxsys</groupId>
        <artifactId>mvvmfx-cdi</artifactId>
    </dependency>
    ...
</dependencies>

Although all other mvvmfx-* artifacts are listed in <managedDependencies> only the ones specifically listed in <dependencies> are actually used.

There is one drawback to this. The <scope>import</scope> attribute is only available in Maven 2.0.9 or later.

Hi tomasz,
thanks for your pull request. This looks interesting. I didn't know this maven feature.
I will have a look at your PR tomorrow.
