::setOptions() method again

1. Created `BaseFilter` class. There is `BaseFilter::setOptions()` which will call setters for each option, this method is automatically being called from constructor. It also includes `BaseFilter::isOptionSupported()` method
2.  Now all filters extend from `BaseFilter`, so all of them support `::setOptions()` and `::isOptionSupported()` methods
3.  Added test for `BaseFilter` methods and option name validation

#### Purpose of This Commit
https://github.com/widmogrod/zf2-assetic-module
As you know this project is using Assetic.

Currently the configuration file of AsseticModule looks like the following:
``` php
<?php
return array(
'assetic_configuration' => array(
    'modules' => array(
        /*
         * Application moodule - assets configuration
         */
        'application' => array(
            'root_path' => __DIR__ . '/../assets',

            'collections' => array(
                'base_css' => array(
                    'assets' => array(
                        'css/bootstrap-responsive.min.css',
                        'css/style.css',
                        'css/bootstrap.min.css',
                    ),
                    'filters' => array(
                        'CssRewriteFilter' => array(
                            'name' => 'Assetic\Filter\LessFilter',
  /* attention ==> */       'option' => array(
                                '/usr/bin/node', // first argument of constructor
                                array('/usr/local/lib/node_modules'), // second argument
                            ),
                        ),
                    ),
                    'options' => array(),
                ),
            ),
        ),
    ),
),
);
```

In my opinion it will seem more *natively-integrated*, if it will look like this:
``` php
<?php
// ...
array(
    'filters' => array(
        'CssRewriteFilter' => array(
            'name' => 'Assetic\Filter\LessFilter',
            'options' => array(
                'node_bin' => '/usr/bin/node',
                'node_path' => array('/usr/local/lib/node_modules'),
            ),
        ),
    ),
);
```

I think you will agree, this looks more *friendly* and more *self-descriptive*

To achieve this all filters must have at least `::setOptions()` method.

README.md must be updated according to this commit
