Updated list commands

@cmuench would like to here your opinion on it.

This interface should make it easier to write "list"-commands with different output (text, json, xml).

• getListHeader ... for the table headers
• getListData ... to collect the data
• getSectionTitle ... to have unified output (maybe not needed)

You dont have to care about the output, since everything all done in abstract::execute().

Found the issue with the tests...

I was able to reproduce the issue with the failing unit tests on my machine.

The problem is that several calls of the filter method caus the issue.
If we split the findInstalledModulesAndFilterThem method in serveral test cases it's working.

/**
     * @test
     */
    public function findInstalledModulesAndCount()
    {
        $this->getApplication()->initMagento();

        $modules = new Modules();
        self::assertCount(0, $modules);
        $total = count($modules->findInstalledModules());
        self::assertGreaterThan(10, $total);

    }

    public function findInsalledModulesAndFilterByCodepool()
    {
        $this->getApplication()->initMagento();
        $modules = new Modules();
        $total = count($modules->findInstalledModules());

        $filtered = $modules->filterModules($this->filter('codepool', 'core'));
        self::assertLessThan($total, count($filtered));

    }

    public function findInstalledModulesAndFilterByStatus()
    {
        $this->getApplication()->initMagento();
        $modules = new Modules();
        $total = count($modules->findInstalledModules());

        $filtered = $modules->filterModules($this->filter('status', 'active'));
        self::assertLessThan($total, count($filtered));
    }

    public function findInstalledModulesAndFilterByVendor()
    {
        $this->getApplication()->initMagento();
        $modules = new Modules();
        $total = count($modules->findInstalledModules());

        $filtered = $modules->filterModules($this->filter('vendor', 'Mage_'));
        self::assertLessThan($total, count($filtered));
    }
    ```
