Offering to maintain feeds_sql

This module has been a great help to me and I'd like to offer to co-maintain/maintain it. I've been tidying up the issue queue recently and have written patches at [#1730990] and #1763872: Field names must be lowercase. No result is output for fields with names containing uppercase characters.

I'm keen to get these changes committed - it's been over a year since the last dev commit and 3 years since the last release. I think that fixing these issues would really improve the module, as they're currently a source of frustration.

Thanks!
