/* jquery targetpop -- makes popup windows out of the 'target' attribute of
 * the matched tags.
 *
 * Only works on <a> tags for now. If jQuery(this).is('a') fails, then nothing
 * is done.
 *
 * (C) 2008 Jeff Shell, Bottlerocket MFG.
 *
 * Example:
 *
 * <a href="..." target="mywin-400x300-resizable-scrollbars" class="targeted"
 *  >...</a>
 *
 * jQuery('a.targeted').targetpop();
 *
 * The above would produce a 400 wide by 300 high window named 'mywin' with
 * resizable and scrollbars set to true.
 *
 * Height can be left off. Other example targets are:
 *
 * `tour-400x600` : 400 by 600, fixed size, all features disabled.
 * `newpage-800`  : 800 by 800, fixed size
 * `newpage-800-resizable-statusbar-menubar` : 800 by 800, resizable, etc.
 * `news-400x600-resizable-scrollbars` : guess.
