Steemd.com update #3

Since the last update:

• Canonical links: Post pages on steemd.com now instruct Googlebot to prefer steemit.com URLs. This means steemd.com will rank lower in search results and the corresponding steemit.com pages will rank higher. (thanks @cryptoctopus, more info)
• The same pages now have a 'View this thread on steemit.com' link to make it easier for users to jump to the same post on the steemit.com website. (thanks @clains)
• Since building from develop @ 4ef97bee, there have been no recurrances of the following crashing bugs: #10, #11, #26, #43, #48 (knock on wood)
• Today was the first crash in 10 days. Reported on GitHub: #71
• Downvotes show correctly, and up/down votes are ordered by date.
• Extra debugging data & vote table in 'advanced mode'
