Release v0.2.0

Fix bug where the action defined for the enter key did not behave as
intended when the supplied action has flags set. Some apps ignored these
and worked flawlessly (Reddit, Chrome, Firefox, ...) while other
apps didn't behave that well (Twitter, F-Droid, ...).

+/**
+ * Data class which holds a parsed theme json file. Used for loading a theme
+ * preset in Settings.
+ * Note: this implementation is generic and allows for any group/attr names.
+ *       FlorisBoard itself expects certain groups and attrs to be able to
+ *       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
+ *  2. A static word
+ *     - transparent (=0x00000000)
+ *     - true (=0x1)
+ *     - false (=0x0)
+ *  3. A reference to another attribute within the SAME theme, as follows:
+ *     @group/attrName -> e.g. @window/textColor
+ *     Note that referencing attributes has its limitations:
+ *     a. Recursive references will cause an exception.
+ *     b. Referencing an previously defined attribute is fine.
+ *     c. Referencing an attribute not-yet defined is also ok, as long as
+ *        the reference can be resolved at the next iteration.
+ *     d. If the next iteration cannot resolve a value, an exception is
+ *        thrown.
+ *  4. If the value is of any other format, an exception will be thrown.
+ *
+ * @throws IllegalArgumentException either at an invalid value or when a
+ *  reference cannot be resolved.
