fix os.sleep(0) causing too long without yielding

[Ocawesome101]

It appears commit 7fecb07 broke os.sleep(0):

while true do os.sleep(0) end

as of oc 1.8.7/1.8.8 this cannot be interrupted, and will crash with too long without yielding, where in 1.8.6 and before this was not the case. may fix #3773

Hi. AGS-Dev here.
You are right about the broken os.sleep(). I just changed the os.sleep() to os.sleep(0.1) and the program works again.
Thank you.

Why not using os.sleep(0.05) since a Minecraft ticks lasts 1/20 of a second (0.05s) ?
I know it only gains 0.05 seconds, but that's nearer from the pre-1.8.6 version.

I got told that 0.05 wouldn't work and 0.1 is minimum. but it works with 0.05 too.
Maybe i change that, or leave it as it is cause its only 0.05 difference.

This is great, I have an unattended program that has this problem and it will definitely trigger this problem after running for a long time.

I use OC to control the reactor, and this problem has caused my reactor to melt down many times.

Thank you so much
