Alexey Ivanov 63fb16ceea lib/helpers: fixed is_valid_packet() 
This commit introduces following changes:
 * Be liberal in what you recieve - do not rely on regexps for packet
   parsing but instead accept anything that can be parsed by JavaScript
   as a number e.g: +1e-17, -0511, 0xDEADbeef, etc
 * Accept both positive and negative counters with explicit / implicit
   sign
 * Provides more strict error checking then regexp, for example
   following strings match previously used '([\-\+\d\.]+' regexp:
   .
   .123.
   .\-+\0\+-.1-

Also while here added more tests.

Closes: #350 #357

Mike Heffner 4223db8a19 Add "sum of squares" to the pre-calculated timer metrics. 
Sum of squares (along with count and sum) can be used to do rapid
calculation of standard deviation/variance over an arbitrary number
of consecutive intervals [1].

David Howell 76c13f03fa Changed test case to ensure sorting 
Changed the test data in timers_multiple_times_even so make sure the
metrics are sorted before getting the median value. If the data was not
sorted, the median value would be 300 instead of 250.

Zach Wily f369dfade2 Support gathering "top" percentile statistics 
Adds support for collecting statistics on top percentiles, instead of
the default bottom percentiles. You specify a top percentile by
using a negative number - so -10 will collect the top 10% of data. It
will emit: mean_top10, lower_top10, and sum_top10.

Using a negative number may seem hacky, but it's convenient and there
is a precedent - referencing an array from the end in some languages
can be done with negative indexes.
