Fixed yisou.com so that SearchAll can work with it in 'page mode'.
Fixed the timer for next/prev page button actions.
Fixed the hostname hash bug. Now 2 identical SE's (such as 2 yahoo.cn) can work at the same time.
Now we use '' labels instead of arrow icons in the navigation buttons.
Set clickSelectsAll for the toolbar's textbox (just like the Google toolbar :)).
Fixed a bug for Mac Firefox. Unlike linux and win32, Mac centers the tabs which breaks the UI. thanks cnhackTNT++ for reporting this. * Refreshing the .xul page in 'page mode' now (mostly) works.
Fixed a bug that baidu.com will show loading animation forever when there's no results at all.
Hides 'please enter your queries above' as early as possilbe in 'page mode'.
Removed several setTimeout calls in the JS code so as to make things a bit faster.
Cached the html so that next/prev page switching is now much more smoothly.
Use WPL.STATE_IS_NETWORK instead of STATE_IS_WINDOW to eliminate bogus progressing actions.
Improved and optimzied the pattern mining algorithm and implementation.
Made the auto-form-submitting code much smarter.
