port: changes to the video settings PR:

- change FPS calculation to use average FPS, use real time instead of render time for interval timing

- remove Maximize Window (you already have a maximize button and it's saved to the INI)

- remove Display FPS Interval from settings (the average user won't care and whoever cares can change it in the INI)

- remove the tickrate override flag and implicit tickrate adjustment in the framerate limit option, instead add one checkbox to uncap tickrate (mostly because I'd like the game to default to the og 60 FPS cap since high FPS is still unstable)

- rearrange some options a bit
