3db6cacf80 Make sure data are in order before displaying them 
If we don't do this, the plotting library draws "backwards" lines which
looks ugly.

Closes #16

5a70de4b0b Also distribute bootstrap non-minified in archives 
Commit 6ae685e added the non-minified bootstrap source to the
repository, but it's still not distributed in the generated archive;
which means that for Debian, issue #20 is not quite closed yet.

e2fee86469 Correct a JavaScript exception for empty distributions 
If you create a distribution but don't write to it, the mean of the
distribution is NaN - which Aeson encodes as `null`. Thus we have to
make sure that when working with the mean, we check for `null`.

0f8352cff3 Break out core metric tracking into a new package 
The new package, ekg-core, contains the metrics store, modules for
defining metrics, and functions for sampling the metrics.

The counter naming is also changed to include a namespace part. For
example "myapp.requests".

Finally the JSON format has been changed to be more self-descriptive.

52bc89f474 Fix memory leak in new counter implementation 
Since we're allocating memory for use outside Haskell, we're
responsible for freeing it. Switched to ForeignPtr to automate this.

64e6ba1259 Improve scalability of counters a lot 
Counters now scale orders of magnitudes better as the number of
writers to the same counter increases. Here's the results on our
current benchmark on a 6 core machine:

        cores
            1       6
before  1.87s  81.09s
after   0.11s   0.32s

Note how the very heavy contention gives a slowdown rather than a
speedup as the number of cores increases, but the new implementation
slows down much less than the old one and is also generally faster.
