This will be a class to handle events, such as custom events implemented
in GDScript/Chat Commands, as well as Twitch Events, such as Raids,
Shoutouts, etc, etc.
Removed General Auto Connect, and replaced it with Auto Connect for
Twitch and OBS, Added OBS Host information. Added Script Storage
variable, to store / fetch Plugin settings.
Added missing toggle for left button and right button. Fixed right
button icon setter.
Added dups of the stylebox for the line edit, as well as storing
original left and right content margins.
Updated resize to add to the content margins for left and right,
depending on if we are creating a left button, or right button.
Ensure that Button is a true flat button, with StyleBoxEmpty.
Added to spacer and container the mouse filter ignore, so that the text
field doesn't get covered by invisible controls.
