Biasing values not stored with Solr

@pau1_m Do you know which version of apachesolr made the switch to using apachesolr_environment_variable?

It looks like this is the patch that made the change:

I've submitted an apachesolr patch that alleviates this issue - there's a switch in there that's blocking hook_form_alter values:

#2492427: Switch in apachesolr_search_bias_form_submit blocking hook_form_alter values

Meanwhile, I'm attaching a patch that in conjunction with the above apachesolr patch allows you to change and save settings.

This is only a partial fix, because the changed setting aren't having any impact on search results that I can see. A complete fix probably involves updating the nodequeue_apachesolr_query_alter function to use apachesolr_environment_variable_get instead of variable_get.

Here's a patch that gets it another step closer. If you remove the switch in the apachesolr function, and apply this patch to nodequeue, then the integration works. You can set bias, and see its effect in the search results.

Unfortunately, it doesn't look like apachesolr's going to accept my patch, so before this is truly complete, an additional submit handler has to be added to save the variables.

Here's the third iteration, a complete patch - with the addition of an extra submit handler, it can now independently get apachesolr integration up and running. Some code cobwebs had to be dusted out, but I've tested this and can say it works like a charm.

the patch from #7 worked for me. Thanks charginghawk!

Thanks! Committed.
