feat: modify pienapple-picture with my remix

- change UI layout to make it looks like the default style of Windows image browser.
- update icons to material design icon for better looks. add lost icons for those new added button at the bottom bar.
- restore window style to normal. remove borderless style.
- delete X button at the right-top corner. disable feature that drag window to move, because all functions provided by native window are restored.
- move prev next image button to the center of bottom bar.
- move navigator view to the right-bottom corner so that it will not overlay on the shown image.
- remove all animation effect, including alpha transition, fade out when exiting and etc.
- delete function that double click windows to exit. now double clicking windows will do nothing. change default value of double click behavior to do nothing.
- change default value of stay on top to false because stay on top is not the default behavior of Windows image browser.
