[htmltmpl] [PATCH] ifdefined

[Tugrul G. <tu...@ga...>]

	Since nobody bothered answering my question on how best to implement
this option, I decided to add to the long list of flags than the short
list of tags :)
	The changes were relatively simple, and seems to work just fine with my
site. Comments on the implementation of the patch welcome.
