Build 77

- Removed a special-case property to make the config more consistent.
    Switching between modes is done with the `to` command, for example:
    ```properties
    idle-mode.to.normal-mode=+leftalt +e
    ```
    However, hint modes used a different, special-case property to define what mode to switch to after selecting a hint:
    ```properties
    hint1-mode.hint.mode-after-selection=normal-mode
    ```
    This special-case behavior has now been removed in favor of the standard `to` command.
    It also allowed me to remove hint2-1-mode and hint2-2-mode, and simply have hint1-mode
    and hint2-mode:
    ```properties
    # Go back to normal-mode when the last letter of the hint is pressed.
    hint1-mode.to.normal-mode=+hint1key
    # Switch to hint2-mode (showing the second hint grid) when the last letter of the hint
    # is pressed while holding leftshift.
    hint1-mode.to.hint2-mode=_{leftshift} +hint1key
    # (hint1key is already defined at the top of the config: key-alias.hint1key.us-qwerty=q w e r t a s d f g z x c v b y u i o p h j k l ; n m , . /)
    ```
    This is a backward-incompatible change, but I believe it's for the best: it improves
    flexibility, and makes the configuration more consistent by reusing the existing `to` command.
