Add custom table row component

[ryanlanciaux]

This allows custom table rows to be created. Documentation still needs to be updated and it would likely be good to state that the names on the custom components will likely change before ver 1 is out (aka customRow and customTableRow components are kind of confusing names).

A rough example of a customTableRowComponent is as follows:

   var CustomRow = React.createClass({
      getInitialState: function() {
        return { editToggled: false };
      },
      handleClick: function(e){
        this.setState({editToggled: !this.state.editToggled });
      },
      render: function(){
        if(this.state.editToggled){
          var cols = _.map(_.pairs(this.props.data), function(col, index){
            return <td><input type="text" defaultValue={col[1]} style={{width: "100%", height: "100%", color: "#CCC"}} />{index === _.pairs(this.props.data).length -1 ? 
              <button onClick={this.handleClick} style={{position: "absolute", right: 0}}>Done</button> : null}</td>
          }, this);
        }
        return this.state.editToggled ?
          <tr>{cols}</tr> :
          <Griddle.GridRow {...this.props} onRowClick={this.handleClick} />;
      }
    });

What's the status?

@ryanlanciaux Is it just me or does this merge use either lodash or underscore without actually require-ing it?

[FirstWhack]

This was never documented in any way.

Does this allow easy editing of the underlying data?
