Allow user-defined limits for search and wget script generation in SearchContext

[agoodm]

Currently when I attempt to generate wget scripts using SearchContext.get_download_script(), setting limit has no effect. There was a comment in the module that said this was a planned feature.

Any reason why this hasn't been implemented yet? This would be useful since the default limit is too small for certain use cases. It seems like something that should be trivial at this point, so correct me if I am wrong.

Hi @agoodm, just a matter of time in getting to this one. However, please badger me and it will get done :-)

@agstephens allow me to badger you about this then :)
