Feature/twig profiler (php-debugbar#362)
* Use Twig_Extension_Profiler as data-source * Add documentation for TwigProfileCollector * Add DebugBar\Bridge\Twig\TimeableTwigExtensionProfiler to measure rendering * Fix & enable xdebug-link-generation in ExceptionsCollector * Enable xdebug-link-generation to TwigProfileCollector (An instance of the Twig_Environment or the Twig_Loader has to be passed to the collector, to be able to resolve the templatename to the filename) Add "ajax"-attribute to xdebug-links (IDEA / PhpStorm-Links should be opened by ajax)

You can provide a `DebugBar\DataCollector\TimeDataCollector` as the second argument of
101101
`TraceableTwigEnvironment` so render operation can be measured.

## Twig (Profiler)
104+
105+
An alternative to `DebugBar\Bridge\Twig\TwigCollector` for newer versions of twig.
106+
This collector uses the class `Twig_Extension_Profiler` to collect info about rendered
107+
templates, blocks and macros.
108+
You need to inject the root-`Twig_Profiler_Profile` into the collector:
109+
110+
$loader = new Twig_Loader_Filesystem('.');
111+
$env = new Twig_Environment($loader);
112+
$profile = new Twig_Profiler_Profile();
113+
$env->addExtension(new Twig_Extension_Profiler($profile));
114+
$debugbar->addCollector(new DebugBar\Bridge\TwigProfileCollector($profile));
115+
116+
You can optionally use `DebugBar\Bridge\Twig\TimeableTwigExtensionProfiler` in place of
117+
`Twig_Extension_Profiler` so render operation can be measured.
118+
119+
$loader = new Twig_Loader_Filesystem('.');
120+
$env = new Twig_Environment($loader);
121+
$profile = new Twig_Profiler_Profile();
122+
$env->addExtension(new TimeableTwigExtensionProfiler($profile, $debugbar['time']));

$debugbar->addCollector(new DebugBar\Bridge\TwigProfileCollector($profile));
