[LyX/master] Change the logic of the indentation setting.

[Richard Kimberly Heck]

commit ca3077b40b38ebd2a18934b892c40c03250d778b

    Change the logic of the indentation setting.
    
    The option here is to NOT indent the paragraph, so make that clear.
    As it was, we would set "Indent" to false in the case of paragraphs
    that do not permit indentation and then write that, uselessly, to the
    LyX file if we wrote any other option (and then keep writing it, even
    if other options were removed). Now, we will write it only if it's been
    explicitly set.
