eb5c9fb Recipe code formatting fix. New recipe for improved APC bytecode support

Discussion
----------

APC recipe

A new recipe to support cache invalidation when using *APC* with *apc.stat* = 0 and compiled code caching turned on. One sometimes want to test things without restarting apache. This recipe overrides *writeCacheFile* in *Twig_Environment* and calls *apc_compile_file to refresh cache.

+ Refreshing modified templates when APC is switched on with apc.stat = 0
+ -----------------------------------------------------------------------
+ 
+ When using APC to cache, apc.stat is 0 and PHP caching of templates is enabled
+ the result won't show until cache is cleared. To get around this one can extend
+ Twig_Environment and force update cache when Twig rewrites the cache::
+ 
+     /**
+      *  Modified Twig Environment for APC bytecode cache support
+      */
+     class Twig_Environment_APC extends Twig_Environment
+     {
+ 
+         protected function writeCacheFile($file, $content) {
+             parent::writeCacheFile($file, $content);
+ 
+             // Compile cached file into bytecode cache
+             apc_compile_file($file);
+         }
      }
