Kranitor #3: jQuerlyfornication ft. The Cascaders

* Classicifation (JS)
 Use addClass instead of attr( 'class' ) whenever possible.
 addClass will manipulate the properties directly instead of
 (re-)setting an attribute which (most) browsers then sync
 with the properties.

 Difference between:
 elem.className
 and
 elem.setAttribute( 'class', .. );

 Just like .checked, .value, .disabled and other interactive
 properties, the HTML attributes should only be used for initial
 values from the html document. When in javascript, only set
 properties. Attributes are either ignored or slow.

* Styling (JS)
 Use .css() instead of attr( 'style' ).

 Again, setting properties instead of attributes is much faster,
 easier and safer. And this way it takes care of cross-browser
 issues where applicable, and less prone to error due to dealing
 with key-value pairs instead of css strings.

 Difference between:
 elem.style.foo = 'bar';
 and
 elem.setAttribute( 'style', 'foo: bar;' );

* Finding (JS)
 Use .find( 'foo bar' ) instead of .find( 'foo' ).find( 'bar' ).
 It is CSS!

* Vendor prefixes (CSS)
 It is important to always list newer (standards-compliant) versions
 *after* the older/prefixed variants.

 So the following three:
 -webkit-gradient (Chrome, Safari 4)
 -webkit-linear-gradient (Chrome 10, Safari 5+)
 linear-gradient (CSS3 standard)

 ... must be in that order.

 Notes:
  - "-moz-opacity" is from before Mozilla 1.7 (Firefox < 0.8)
    Has not been renamed to "opacity" since Firefox 0.9.
  - Removed redundant "-moz-opacity"
  - Added "filter: alpha(opacity=**);" where missing
  - Fixed order of css3 properties (old to new)
  - Add standardized css3 versions where missing
    (some 'border-radius' groups didn't have the non-prefixed version)
  - Spacing
  - @embed
  - Shorten hex colors where possible (#dddddd -> #ddd)
    $ ack '#([0-9a-f])\1{5}' --css
    $ ack '#([0-9a-f])\1{2};' --css
