+ *       color the controls accordingly. See 'ime/themes/floris_day.json'
+ *       for a good example of which attributes FlorisBoard needs!
+ *
+ * @property name A unique id/name for this theme. Must only contain certain
+ *  characters: upper/lower case letters, numbers (not at the beginning!) or
+ *  an underline (_).
+ * @property displayName The name of this theme when shown to the user. Can
+ *  contain any valid Unicode character.
+ * @property author The name of the author of this theme. Should be your
+ *  username on GitHub/GitLab/BitBucket/... or your full name.
+ * @property isNightTheme If this theme is meant for display at day (false)
+ *  or night (true). This property is only used to auto-assign this theme to
+ *  either the day or night theme list in Settings, which is used when the
+ *  user wants to auto-set his theme based on the current time.
+ * @property rawAttrs Map which holds the raw attributes of this theme. Note
+ *  that the name of this property is 'attributes' within the json file!
+ *  Attributes are always grouped together. This ensures a better structure
+ *  and easier storage. The group- as well as the attr-name has the same
+ *  limitations as the theme [name].
+ *  Attribute values can be of different format:
+ *  1. A color
+ *     Either #RRGGBB or #AARRGGBB (case-insensitive) -> e.g. #A034FF23
