Clearer theming options

[HenryWales]

I guess the theme feature is meant to allow total overhauls.

But the existing themes seem to only change one thing or two, and there is no info in the UI at all on what is changed

Testing I noticed these changes:

Default-mod: The only thing I noticed is that instead of an overflowing "word." being sent to the next line, it splits the word from the punctuation sign and only overflows the punctuation sign if possible. Maybe useful for some languages, strange with an european one. Lingocracy: Different style of word highlighting, much more discrete. Same breaking difference as default-mod compared to default. Lingocracy: dark mode of the above Night Mode: dark mode of default-mod? White Night: night mode, but highlighted words are also white Chaosarium light: normal breaking rules, different style of highlighting compared to default, different "word action box" theme.

Full-theme support is also good, but I propose to split some theme options:

• Light mode or Dark mode
• Highlighting style
• Text breaking rules

Hi! That's an interesting suggestion! I'm not the one who implemented themes, so I did not really focused on this issue until now.

I guess I can add some words in the documentation, I may add a more detailed explanation in the future!
