Horizontal text alignment

[jkevingutierrez]

Is your proposal related to a problem?

Horizontal text alignment (left, center, right, justify) is a common option used in text editors. It would be great to have it by default

Describe the solution you’d like

Add 4 new options to align text (Images or other blocks could be aligned too)

Describe alternatives you’ve considered

We are still able to create a custom block to achieve this. But there are some considerations that could complicate it a little bit:

• It cannot be a block component or you wouldn't be able to combine it with other Blocks. Like having an H2 centered.
• It cannot be a InlineStyle as it won't be a "block" element meaning that it won't have a container to align the things in.

Finally, it needs to be an Entity which are a bit more complex to implement than InlineStyles and Blocks.

As this seems to be a common thing used in editors, it would be good to have it by default on Draftail.
