Combined feeds block

This is a great idea for a new feature! I've downloaded this module, enabled it and applied the patch from #2. There are a few issues that I've encountered and configuration ideas I had in the process of setting up:

1. When I try to apply the patch, I get Reversed (or previously applied) patch detected!. Being that this is the first time I've downloaded and installed this module, I'm unsure of why this would be happening.
2. After clearing the cache, the combine tab will show up when editing the social feed settings, but it looks like the facebook link disappears from the admin menu for some reason. Combine is in its place.
3. It might make sense to have the twitter and facebook checkboxes already selected. It would also be great to include instagram as an option.
4. When adding the block to the page, numerous notices pop up on a bunch of different lines within the .module file (this is a condensed list):
   

   Notice: Undefined index: type in socialfeed_facebook_data() (line 293 of socialfeed.module).
   Notice: Undefined index: type in socialfeed_facebook_data() (line 298 of socialfeed.module).
   Notice: Undefined index: link in socialfeed_facebook_data() (line 307 of socialfeed.module).
   Notice: Undefined index: meta in socialfeed_combined_sort() (line 534 of socialfeed.module).
   Warning: usort(): Array was modified by the user comparison function in socialfeed_combined_posts() (line 523 of socialfeed.module).

5. I noticed that the patch dropped the combine.tpl.php file into the root folder instead of the templates directory. I manually moved the file over and the block rendered on the page. Both the twitter and facebook items are showing as expected, ordered by date.

Hopefully this helps! Let me know if you'd like any other information provided.
