This macro is similar to <<timedreplace>>, but instead of replacing one block of text with another, it just re-runs a passage section, re-drawing the text and running the contained macros again.

Much like <<timedreplace>>, the transition between each rewrite is handled by CSS. Here's a default "fade-in" transition:

.timedloop.replacement-in {
	opacity: 0;
}
.timedloop {
	transition: 1s;
	-webkit-transition: 1s;
}
.timedloop.replacement-out {
	display:none;
}

You can easily modify this CSS. If you want an "instant" transition, for instance, change "opacity: 0;" to "display:none;"

New: This now takes CSS time values, which are decimal numbers ending in "s" (for seconds) or "ms" (for milliseconds).

Here's a usage example:

<<set $red=1>>
<<timedloop 1s>>You have <<set $red += 1>><<print $red>> seed pods.<<endtimedloop>>

The text will initially read "You have 2 seed pods.", then change to "You have 3 seed pods." after 1 second, then "You have 4 seed pods." after another second, and so forth until you leave the passage. The time value is in half-seconds, like <<timedreplace>>.

Known bug: When you click a link to leave a passage, the loop will still run while the passage is transitioning out. This may cause unexpected behaviour (if, for instance, a <<timedgoto>> is inside the looped code).

Implementation details:
* If inserted text appears and descends below the bottom of the screen, the page should automatically scroll down to make it visible.
* Note: due to the way the browser and Twine interact, any changes made by code inside a <<timedloop>> tag after the first iteration will be forgotten if you use the Back or Forward browser buttons. This means that if you put long-term variable changes that affect future passages inside one, you should disable the Back button.

Version history:
* 11-4-2013: Fixed bug where the timeout wouldn't expire if you clicked a "refresher" link to the same passage.
* 5-4-2013: Initial.
