The script for the settings page included a large amount of duplicated code, so I refactored it to put that reused code in functions instead. I also refactored other code, such as massively simplifying the function that converts the user's settings to checked radio buttons.
Additionally, I refactored the "Individual wiki settings" table to actually be built using a table, instead of a structure that only appears to be a table.
I also made various other minor adjustments to the Settings page:
* Adjust the formatting of the "icon legend" box to be consistent with the other boxes on the page.
* Replaced the emoji 🍃 instead of the Tibetan character ༄ to represent BreezeWiki. The Tibetan character was rendering much smaller than the emoji in the other boxes. But regardless, it's better not to use characters non-semantically.
* Add a border around the "individual wiki settings" table, for consistency with the other boxes on the page.
