Allow indentation using space or tab characters

Currently, if you try to do something like:

This line is normal
    This line is indented
This line is normal again

LinkedIn will "eat" away empty spaces, so it will look like this:

This line is normal
This line is indented
This line is normal again

AuthoredUp could "fix" this by converting empty spaces into special "non breaking empty spaces", so they will remain in the post.

Potential downside: A few of my posts that used this empty spaces did very poor in terms of "reach". I am not sure this has anything to do with empty spaces, or just a coincidence, but it is something to be aware of.
