Improve textImg component

[FroudeDescartes]

This is connected to issue #76 Add options for this component to:

• [x] add title prop
• [x] present only the text (text is still able to span multirows)
• [x] change the bg color (have it like a status: on, off, pending, higlight)
• [x] overview- this is only for developers, so they will know what does this component do description (default value explains how to use component if no description is inserted)
• [ ] layout (idea is to maybe create a single .js file that will contain Class, which can be later down the road inherited to the desired component an reused the prop create a single component, instead of couple of them, that can have all the necessary logic integrated and used depending on layout selection)

@jpradocueva can you attach here, or send me on Slack a spreadsheet file that represents usecases for different properties in different components?

@FroudeDescartes I am closing this issue. Layout property is not a priority in this development. The rest of items have been completed.
