(ResultsDashboard.prototype.push): Appends an iteration results;
(ResultsDashboard.prototype.toJSON): Converts the iterations results to JSON format.

(RecordTable.prototype.clear): Clears the results table.
(RecordTable.prototype._showTitles): Shows the header titles and appends the sub-titles to a queue.
(RecordTable.prototype._showHeader): Shows the table header titles.
(RecordTable.prototype._showEmpty): Shows an empty table cell.
(RecordTable.prototype._showValue): Shows a number value in the results table.
(RecordTable.prototype._showSamples): Shows a button for the sampled data graph.
(RecordTable.prototype._showTest): Shows the results of a single test.
(RecordTable.prototype._showSuite): Shows the results of a single suite.
(RecordTable.prototype.showRecord): Shows a single iteration for a single test.
(RecordTable.prototype.showIterations): Shows the results of all the suites of the iterations.

(ResultsTable): RecordTable was renamed to ResultsTable.
(ResultsTable.prototype.clear): Clears the table element.
(ResultsTable.prototype._showHeaderRow): Shows a row in the results table header.
(ResultsTable.prototype._showHeader): Shows the results table header.
(ResultsTable.prototype._showEmpty): Shows an empty table cell.

* Animometer/resources/sampler.js:
(Sampler.prototype.startSampling): Use forEach.
(Sampler.prototype.sample): Use forEach.
(Sampler.prototype.toJSON): Converts the sampler data to JSON format.

* Animometer/resources/strings.js: Added.
This new file will be used to associate the strings used by the benchmark
with IDs. A string can be changed in one place without having to change
all the instances of this string in multiple files. There two groups of
strings in this file. The first one is used by the UI elements and the second
group is used when constructing the results JSON.

(window.benchmarkRunnerClient.didRunSuites):
(window.benchmarkRunnerClient.didFinishLastIteration):
Make benchmarkRunnerClient uses ResultsDashboard instead of _iterationsSamplers
Get the JSON from ResultsDashboard.toJSON() and pass it to ResultsTable.showIterations().
Also set the textContent of the "#json" textarea with the results JSON.

(showResults): Delete unneeded code.
(showJson): Shows the "json" section.
(showTestGraph): Rename showGraph() to be showTestGraph().
(showTestJSON): Shows the JSON of a single testResults.
(showGraph): Deleted.

Use the string table instead of putting literal strings.

* Animometer/tests/resources/stage.js:

Fix the parameters which are passed to RecordTable.showRecord().
