Consider query string field for internal redirects

[annaf-dev]

Please have a look, if this fits your code structure.
In my local Sitecore instance it works as expected.

See issue #27 for more information.

Hello Anna. I am totally open to merging / accepting this pull request. Can you please provide a reason why this is necessary? I am totally open to this, just curious.

Thank you,

Andy

Hello Andy,
we have the case that we want to redirect a shortlink like www.domain.com/shortlink to an internal Sitecore page with a query string (which will be handled by a controller action) like www.domain.com/path/to/sitecore/page?query=string.
I use a Simple Redirect for this case. At the "Target" field I insert an internal link and there is a field "Query string" which will be appended to the internal link. Normally. But this field was not considered by your plugin so far. That's why I added it.
I hope this makes it clear. :)
Anna
