[IMPROVEMENT] UX for close window button of the player

[mfkl]

A UX suggestion.

These buttons are all very handy, but I'd put the closing button somewhere else:

• You might inadvertently close the window when clicking on other options, since they are pretty closely displayed.
• People are used to having the close button at the top left/right, but I guess you want to keep a no title bar design. Maybe a background-less X that would appear over the video could be an option? Don't know.

Just some first impression feedback, feel free to close this :)

to add onto this, it seems that since the title bars were removed from the external mpv windows, it became impossible for me to use Win + arrow keys to snap the player window to edges of my monitors. would it be possible to bring back title bars on mpv player windows (maybe as an option)?

I added a checkbox to disable MPV borderless mode. It still plays nicely with loading of layouts, so that's good.

I rarely use the close button since pressing the escape button also works. I just added a shortcut to close all player windows using shift + escape. Will close this issue for now.
