the decision to have a space after `function`, so `function () {}`
instead of `function() {}` is based on douglas crockford's javascript
code conventions [1].

* igorw/fix-htaccess:
  also disable apache MultiViews
  remove -d from .htaccess RewriteCond

MultiViews is a content-negotiation option for apache that will, when requesting /resource try to serve /resource.ext. if you have a blog.php this can lead to /blog serving you blog.php instead.

this can be quite common with mounted apps.

great thanks to Rafael Filipek for discovering this.

this caused issues when you try to mount a blog.php under /blog. apache serves you blog.php although blog.php is not a directory.

removing the RewriteCond resolves the issue.

if we don't do this, it's impossible to use route parameters in before
handlers.

you can get the current version by calling the phar without arguments:

    $ php silex.phar
    Silex version 1ee6b36

there is only one single `update` command:

    $ php silex.phar update

this will fetch the latest version of the phar from silex-project.org
and replace the current one with it.

this makes it easier for users because they can easily update. we could
potentially even provide a changelog on running the command.

this commit also introduces a Silex\Application::VERSION constant that
currently is set to the current git SHA-1, as I proposed in PR 33. This
is done by the Compiler. It can later be adjusted to use `git describe`.

this is an implementation of PR 35 without the console component.
