Change rule of importing and exporting pacakge

[QilongZhang]

Now, SOFAArk support the behavior of importing and exporting package; the following configuration

<export>
    <packages>
        <package>a.b</package>
    </packages>
</export>

, means that all classes start with a.b would be exported, e.g. a.b.C, or a.b.d.E. Sometimes, we find it's not very convenient.

With full consideration，in SOFAArk 0.3.0, we would change the rule of exporting and importing behavior. It's so pity that it would NOT be compatible with previous version. No matter import or export package, we define two pattern of configuration.

• package-level configuration, e.g. a.b, it just represents classes with accurate package name equals to a.b;

• package-level configuration, e.g. a.b.*, it represents classes whose package name starts with a.b

These two rule would also be applied to denyImportPackages
