fix typo for resize cursor
enable ie opacity, improve gradients
add IE 8 icon fix for icon fonts using :before and :after pseudo elements

IE8 does not present the icons properly on page load, even though the icon font is loaded and available.
This little hack solves the issue.
bind secondary events on document instead of window, provide shortcuts for globals, cleanup
add html5shiv.js
add BrowserController with notSupported action to provide a selection of new browsers to users using IE7 and below
check for <=IE7 and redirect those users to the new Browser::notSupported page.
provide a more general support layout
use the new support layout
js translations can now have a context that is replaced in the message, shortcut is now wasabi.i18n
refactored url creation to its own function
add a new one third class span1_3
use more mixins (browser support)
suppress unkown target warnings
replace jQuery File Upload Plugin with a custom Multi File Upload plugin

reasons against jQuery File Upload plugin:
- way too big (>30k minified with all required components)
- structure not very readable/maintainable for customizations
- ui handling of iframe transport uploads is ugly

reasons for a custom jQuery Multi File Upload plugin:
- smaller size (14k minified with almost the same functionality of jQuery File Upload )
- tailored for responses from the wasabi backend
- event driven architecture with no callbacks in the plugin settings
add KeyValueBehavior
use the new KeyValueBehavior for core settings
rename cache_time to cache_duration
setup available cache durations from CoreSetting model
add new find type 'allKeyValues' to KeyValueBehavior
