slideshare 6.x-1.0-beta3

I (rootwork) have taken over maintainership of this module. With that, I'm releasing 6.x-1.0-beta3 (the first new release in more than two years!), which rolls in two bugfixes that were in the development branch:

• #1062102 by pescetti: warning: Parameter 6 to emvideo_slideshare_video() expected to be a reference, value given
• #760698 by wojtha: Regex To Extract Embed Code over-simplified and defaults to Slideshare for all emvideo

Both of these fixes were widely tested and approved by the community.

I hope to begin addressing other issues from the queue, moving toward a stable 1.0 release shortly. Simultaneously, I'm going to be working on a 7.x branch that will integrate with the media module.

Finally, I'm still getting the hang of Git and project maintenance (which is why this jumped two beta numbers, from b1 to b3, as I forgot to update CHANGELOG.txt on the first round), so feedback is definitely welcome!
