Bump for v0.8.2

Update internal glide repos for v0.8.0 (decred#563)

Bump for v0.7.0

Update to v0.6.1

Notify only relevant stake txs, not all. (decred#447)

I misunderstood an old dcrd comment and thought that all stake
transactions were notified irrespective of whether they were actually
relevant to the wallet or not.  Fix this by only including those that
pass the tx filter for block connected notifications.  Rescanned
blocks already handled this correctly by only including the relevant
stake txs.

Bump for v0.5.1
