New DataGrid themes available - ocean and balsam

With the release of <InfiniteTable /> v5.0.0 we've added two new themes: ocean and balsam.

Now you have a selection of themes to choose from: default, minimalist, ocean and balsam.

To apply a theme, you have to set the className "infinite-theme-name--THEME_NAME" to any parent element of the <InfiniteTable /> component (or even on the component itself).
