Update some javadocs.
Make Timer.Context closeable.

This way it can play nicely with Java 7's try-with-resources.
Renamed Sample to Reservoir.

Should have followed @joewilliams's lead on this a while ago with Folsom.
Remove the old, outdated Markdown docs.
It is the future now.
Make registry fields final in reporter builders.
Oh hello huge chunk of dead code!
Log debug error with buffer pool loading.
Added rate and duration units to JmxReporter.
Added ThreadDeadlockHealthCheck.

Closes #343.
Added min, max, mean, and stddev to Snapshot.
Remove min/max/mean/stdev from Histogram + Timer.

Rename reporter base to ScheduledReporter.

Also, moved all the rate/duration conversion logic up into it.
Modernized the release notes for 3.0.
Upgrade to SLF4J 1.7.5.
