Keymap: New preference to open folders on single click in file browser

Introduce a new keymap preference to navigate into folders by clicking on them once instead of twice.
Makes browsing folders faster albeit non-standard, so keeping this off by default for now.

Does not affect Industry Compatible or other keymaps.

It is still the possible to right-click to open context menu, hold Ctrl or Shift to select multiple items:

{F10651030, size=full}

----

Keymap preference:

{F10652759, size=full}
