I've just updated this library with quite a few new features, as well as many small tweaks and fixes.

Here's the full changelog:

• Added "timer_set_pause" and "timer_get_pause"
• Added the "repeat" argument to "timer_set". You can now use the timers the same way you'd use Javascript's "setInterval()".
• Added support for custom tick rates, allowing the use of timers with projects that utilize delta time.
• Removed "timer_system_init".
• Made the code more consistent.
• Made the example look fancier.
• Rewrote the description.
• Changed the license to MPL 2.0.
