Fix: Replace URI placeholders before applying base URI, in order to avoid duplicate slashes introduced due to URI placeholders. (#48)

// now correctly returns "http://example.com/path"
// instead of previous   "http://example.com//path"
$browser = $browser->withBase('http://example.com/');
echo $browser->resolve('{+path}', array('path' => '/path'));

// now correctly returns "http://example.com/path?q=test"
// instead of previous   "http://example.com/path/?q=test"
$browser = $browser->withBase('http://example.com/path');
echo $browser->resolve('{?q}', array('q' => 'test'));
