Safari complains about "Slow Script" if GMail is left open and machine is busy

<rdar://problem/4649516>
Turn off slow script dialog or crank up time that makes it come up

<rdar://problem/4963589>
Slow script warning is displayed after closing of PROMPT or PRINT dialog

Re-do the way script timeouts are handled. No longer use a unix timer that sends signals. Instead, add a
tick count and increment it in loop bodies. If the tick count reaches a threshold, do a timeout check. If the total time executing
is higher than the timeout value, (possibly) interrupt the script. The timeout checker also adjusts the threshold dynamically
to prevent doing the timeout check too often.

• JavaScriptCore.exp: Remove pause and resume calls.

• JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj: Add winmm.lib.
