[WebProfilerBundle] removed next pointer class in a template

It's not needed as there is nothing after the span here, eg. on a 404, see :
http://awesomescreenshot.com/0d5149an51

It displays "n/a ::".

[2.1][Process] Fix Process timeout

This PR fixes timeout in the process component.
Timeout can now be float values. The precision of the timeout is given by the `Process::TIMEOUT_PRECISION` constant.

Note : The timeout works when running the process with the `Process::run` method. When using the `Process::start` method, the `Process::checkTimeout` method should be regularly triggered to perform a check.

example :

```php
$process->start();

while ($condition) {
    // some stuff
    $process->checkTimeout(); // throws an Symfony\Process\Exception\RuntimeException if timeout is reached
    usleep(1000);
}
```
