Hello, everyone!

• Added support to automatically match FPS with the current refresh rate of the display.
• Fixed an issue, where player was unable to enter antigravity fields from the sides.
• Fixed an issue, where player could get a sudden speed boost while falling between 2 portals.
• Hopefully fixed an issue, again, where player would phase through the ceiling during gravity switch.
• Modified signs and popup text boxes to work at constant pace, not affected by the "game speed" setting.
• Plenty of various code improvements and corrections.
• Small level adjustments.

This is a big one in a small package! If you have 140Hz, 240Hz or whateverHz display, you can really feel the smoothness now: The game is no longer locked at 60fps! There's also plenty of adjustments related "game speed" -option. There were some issues, like missiles had unfair maneuverability and one of the bosses could bug out. These are now sorted along with other minor issues.
