- 870, 877, 878: growfield plugins send wrong value when empty textarea. Now use another plugin for autogrow.

-/** jQuery textarea autogrow plugin
- *   jQuery.1.2.6 required
- * 
- * optional parameters: // $(elem).growfield( options ) 
- * * * * * * * * * * * * * * * * * * *
- * auto - bool // default = true // if false, ctrl + up/down are enabled
- * animate - bool // default = true
- * before(jEvent), after(jEvent) - callbacks // 'this' will be the dom object
- * min - integer - height in pixels // default = min-height ? css.min-height || initial height
- * max - integer - height in pixels // maximum size // default = css.max-height || none
- * restore - bool - restore original size on blur (and back to growed on focus) // default = false
- * speed - integer - animation speed. not a jquery parameter // default = 300 (ms)
- * offset - integer - bottom offset // default is calculated for each textarea separately // i don't recommend to touch it :) 
- * 
- * additional functions (public interface):
- * * * * * * * * * * * * * * * * * * *
- * $(..).increase( [step] ), decrease( [step] ), growTo( height ), growToggleAuto( bool ), growToggleRestore( bool ), 
- * growSetMin( integer ), growSetMax( integer )
- * 
- * notes
- * * * * * * * * * * * * * * * * * * *
- * parameters may be set in html attributes // tag attributes have priority 
- * <textarea autogrow=1/0 animate=1/0 speed='' line='' min='' max='' restore='' step=''></textarea>
- * 
- * increase and decrease functions are working only in auto mode
- * 
- * opera:
- * in opera, if you don't have border style for textarea, plugin will set it (opera hides borders in overflow:hidden mode). 
- * in auto mode it won't work at all. More than that, opera returns border:2px solid #00000 even if you don't set it. :(
- * 
- * known problems: 
- * after restore (onfocus) with animation textarea sometimes looses cursor. :( // ff2, ie7xp
- * when reached maximum height, opera will jitter on every keydown :( // opera < 9.5
- * 
- * ctrl + up/down: 
- * in opera and ie this shortcut doesn't work properly. But you may use ctrl + whatever + up/down.
- * 
- * three things that make possible scrollHeight update in opera < 9.5:
- * (actually, we don't need scrollHeight in opera < 9.5, but we need something to be updated when typing)
- * height: auto, toggle overflow to hidden and back to auto, and (!!!) padding >= 4px (am i crazy?!)
- * we need textarea because only in this way we can calculate height with all inherited styles
- * 
- *  @author: johann kuindji (www.kuindji.com, www.stuffedguys.com, www.stuffedtracker.com) jk@kuindji.com
- *  @version 1.1
- *  
- *  example: 
- *  $('textarea').growfield();
