Enable custom font entry when changing font through the command line

[leduyquang753]

This allows the user to type a custom font name into the command input box then press Enter to set a custom font in the Change font family command.

This also fixes an issue where the settings page does not reflect the current settings when directly accessing /settings.

This doesn't work with single list command line. Plus why go through all the issues of adding a defaultBehavior() and changing half the command line script when you could just use input: true like the pace caret fields?

{
  id: "setPaceCaretCustom",
  display: "custom...",
  input: true,
  exec: (input) => {
    setPaceCaretCustomSpeed(input);
    setPaceCaret("custom");
  },
},

Am I missing something?

[leduyquang753]

Well to be honest I didn't notice that existing custom implementation, but anyway I feel it's better to directly type in the custom name instead of having to pick custom beforehand. If you still feel like this is unnecessary then I will switch.

I think I would prefer the command line to be consistent in its functionality, so ideally you should use the already present input behavior.

Plus as I mentioned your implementation does not support single list command line.

Could you explain to me the config load promise change? You seem to know more about async stuff than me

[leduyquang753]

There are two points where I made promises:

1. configLoadPromise is waited for by fillSettingsPage. Because immediately using JQuery to set active option buttons after creating those option buttons seems to not work (properly), I add the active status directly into the buttons when filling them into the settings page, which requires the current config to be loaded.
2. settingsFillPromise is waited for by updateSettingsPage so that by the time the function is executed, the settings page is sure to have the necessary buttons to be worked on and set active according to the current config.
