Implemented custom meta props. Fixes #1634

[smirea]

Ref: #1634

This allow creating own meta properties for fields via the reducer:

combineReducers({
    form: form.plugin((state, action) => {
        if (action.type !== 'redux-form/CHANGE') return state;
        return setIn(state, 'fields.' + action.meta.field + '.myCustomProp', true);
    })
});

results are passed to the meta object:

<Field name='foo' component={renderFancy} />

const renderFancy = ({input, meta: {myCustomProp}}) => 
    <input type="text" {...input} style={myCustomProp ? {color: 'red'} : null} />

Current coverage is 100% (diff: 100%)

Merging #1684 into master will not change coverage

I wonder if this should be documented somewhere. It seems like a pretty obscure "feature".

Good job implementing it, though!

In the current redux-form version you can only write plugin for specific forms.
I use dynamic form names so I don't see how I can add a plugin to that.
Any other way I can access the main redux-form reducer or add custom meta properties any other way?
