gitignore packages
Revert "prefix package names to allow easy install of local forks"

Trying to use the version number instead.  Having these seems to confuse myget and it builds both metrics and Yammer.Metrics.

This reverts commit ae29c114eefbf8546315ca2926f3535182228cf5.
fix units on RescaleThreshold and initialize _nextScaleTime.

RescaleThreshold was being initialized to ns even though we were
comparing to ticks (100ns).

_nextScaleTime was not being initialized, so add that to Clear().
