commit 27bbf6507db26ae9d53054ce908df203beefc3c8
Author: Bastian Waidelich <*****>

     * !!!changed view helpers once again!!! link view helpers reside in the link subfolder now. For each link view helper there is a corresponding uri helper now. Check out for a working example.
     * TagBuilder->setContent does not apply htmlspecialchar() on the the tag contents, as that does not really makes sense - if you really need to escape tag contents, you gotta do it yourself now.

    * Backported major changes from Fluid v5 to Fluid v4
    * !!! Many of these changes are not backwards-compatible! Please read this if you have written custom ViewHelpers!
    * Introduced Shorthand Syntax for calling ViewHelpers
    * Core:
    ** Lots of internal cleanup and refactorings.
    ** !!! Complete restructuring into subpackages.
    * ViewHelpers:
    ** !!! The base classes of ViewHelpers changed to Tx_Fluid_Core_ViewHelper_AbstractViewHelper and Tx_Fluid_Core_ViewHelper_TagBasedViewHelper. Please adjust your ViewHelpers!
    ** !!! $this->variableContainer has been renamed to $this->templateVariableContainer
    ** !!! the view is not in $this->variableContainer anymore. Currently there is no way to fetch the View from a ViewHelper.
    ** Introduced a new $this->controllerContext containing the context variables of the controller
    ** !!! The request can be now found in $this->controllerContext->getRequest()
    ** !!! The URIHelper has been renamed to URIBuilder and can be now found in $this->controllerContext->getURIBuilder()
    ** Introduced a new ViewHelperVariableContainer, available in $this->viewHelperVariableContainer to pass data between ViewHelpers. Should only be needed in very rare cases.
    ** !!! Removed <f:format.htmlEscape> ViewHelper! Please remove these declarations in your template! Escaping of object accessors is now automatically done, see next point.
    * !!! ObjectAccessors {...} are now automatically HTMLspecialChar'd if not used as an argument to a ViewHelper. This is done using a new ObjectAccessorPostProcessor. Lateron, this will be made configurable.

    [+BUGFIX] Fluid: Replaced SplObjectStorage by Tx_Extbase_Persistence_ObjectStorage to be PHP 5.2-compatible (which ships with a broken implementation of SplObjectStorage)
    [!!!][~TASK] Fluid (Core): Renamed ConditionViewHelper and TagBasedViewHelper to Abstract*ViewHelper as per CGL. (backported from Fluid package r4840). To be backwards-compatible, TagBasedViewHelper.php still exists and will write an entry to TYPO3s deprecation log if used.
