Adding precision rounding to the accumulator. This means that now every
input metric will get rounded at collection, rather than at write (and
only for the influxdb output).
This feature is disabled for service inputs, because service inputs
should be in control of their own timestamps & precisions.
This will basically make the root directory a place for storing the
major telegraf interfaces, which will make telegraf's godoc looks quite
a bit nicer. And make it easier for contributors to lookup the few data
types that they actually care about.

Reuses same logic as the plugins for filtering points, should be only
a marginal performance decrease to check all the points before writing
to the output.
Added examples to the README as well (for generic pass/drop as well as
output pass/drop/tagpass/tagdrop).

Currently adding with time is broken, because InfluxDB does not support
using precision for timestamp truncation both with and without
timestamps. This will be re-enabled once we fix InfluxDB to use the
precision argument for truncation in all cases, and a "unit" argument
in the line-protocol for adding points with non-nanosecond stamps
Fixes#175
