Add dedicated methods to control options, deprecate withOptions()

[clue]

This changeset deprecates the generic withOptions() method and adds dedicated methods to control all options:

// old: deprecated
$browser->withOptions(['timeout' => 10]);
$browser->withOptions(['followRedirects' => false]);
$browser->withOptions(['obeySuccessCode' => false]);

// new
$browser->withTimeout(10);
$browser->withFollowRedirects(false);
$browser->withRejectErrorResponse(false);

Supersedes / closes #155, thanks @WyriHaximus for the original version!
Resolves #154
Builds on top of #170
