* Show the difference between edited statuses

Diff each status against the previous version, comparing the different
HTML as XML to produce a structured diff.

Mark new content with `<ins>`, deleted content with `<del>`.

Convert these to styled spans in `ViewEditsAdapter`.

* Update diffx to 1.1.1

Fixes issue with diffs splitting on accented characters

* Style edited strings with Android spans

Don't use HTML spans and try and format them, create real Android spans.

Do this with a custom tag handler that can add custom spans that set the
text paint appropriately.

* Lint

* Move colors in to theme_colors.xml

* Draw a roundrect for the backoround, add start/end padding

Make the background slightlysofter by drawing it as a roundrect.

Make the spans easier to understand by padding the start/end of each one with
the width of a " " character. This is visual only, the underlying text is not
changed.

* Catch exceptions when parsing XML

* Move sorting in to Dispatchers.Default coroutine

* Scope the loader type

* Remove alpha
