release 3.6

- No longer select all text if selection (or caret position) was changed by
  application and `selectAllOnFocusPolicy` is `once` (the default). (issue #983)
- FormattedTextField and Spinner: `selectAllOnFocusPolicy = once` behaves now
  as `always` (was `never` before), which means that all text is selected when
  component gains focus. This is because of special behavior of
  `JFormattedTextField` that did not allow implementation of `once`.
- Client property `JTextField.selectAllOnFocusPolicy` now also works on
  (editable) `JComboBox` and on `JSpinner`.
- Added client property `JTextField.selectAllOnMouseClick` to override UI
  property `TextComponent.selectAllOnMouseClick`. (issue #961)
- For `selectAllOnMouseClick = true`, clicking with the mouse into the text
  field, to focus it, now always selects all text, even if
  `selectAllOnFocusPolicy` is `once`.
