allow replace $_SESSION by ArrayAccess instance

Sometimes you need to use custom session handler, this patch adds support for that.

Hi,

Thanks for the suggestion and change. I am planning an upcoming release (branch nextgen) and have made some significant changes to the core code and changed things such that code storage is handled by something called a StorageAdapter.

The session support is replaced by the StorageAdapter\Session class, and we could do an ArrayAccess one that follows your method.

Also, at first glance at your code, it looks like when a code is stored, it would wipe out captcha data from other namespaces (for example, $_SESSION['securimage_code_value'] = array($this->namespace => $this->code);). It looks like if a previous code in another namespace was saved, this would destroy that and just save the new namespaced value.

Thoughts on the last comment and the upcoming changes?

Hi,
solution with adapter is definitely better but I needed quick and easy solution for current version. I'm using this pull request as a patch for my project's libs. It's not ideal solution but it's working and it's relatively clean.

Thanks for the notice about namespaces I missed that - it's fixed now.
