Fix a bug that does not persist some settings

[Tristar7]

Changing 'Show page divisors' option simply doesn't save and directly reverts to its previous state. Can be seen just by closing and reopening ESGST options.
If it was enabled before (either before version update or through setting import) it stays enabled.
Only on Chrome/Opera, works on FF.
No errors in console.

What version are you using on Chrome/Opera? I really don't think this has anything to do with the browser, but with the version you're using and how long you've been using it.

Should be fixed, it was not related to the browser.

Out of interest how did that only affect some settings?

You can check the commit above, it's related to the function ESGST.getOldValues.

It's the settings that were migrated when includes/excludes were implemented. They were being overwritten every time instead of only the first time.
