use RESUtils.click to open comment form in bitcoinTip's "tip publicly" instead of jQuery .click()
Chrome Canary is ignoring $().click(), so better safe than sorry.
Merge pull request #514 from andytuba/issue_514

bitcoinTip's "tip publicly" does not open comment form

I'm merging this, but per the discussion it's a valid point that we should probably look at other .click() calls and test them in Canary, etc.  Could this be related to the change that was made regarding FF23?
