Reviewed by Benjamin Poulain.

Updated associate-bug.php to match the new database schema.

* public/include/json-header.php:
(require_format): Removed the call to camel_case_words_separated_by_underscore since the name is
already camel-cased in require_existence_of. This makes the function usable elsewhere.

* public/privileged-api/associate-bug.php:
(main): Changed the API to take run, bugTracker, and number to match the new database schema.
Also verify that those values are integers using require_format.

* public/v2/analysis.js:
(App.AnalysisTask.label): Added. Concatenates the task's name with the bug numbers.
(App.Bug.label): Added.
(App.BugAdapter): Added.
(App.BugAdapter.createRecord): Use PrivilegedAPI instead of the builtin ajax call.
(App.BuildRequest): Inherit from newly added App.Model, which is set to DS.Model right now.

* public/v2/app.css: Renamed .test-groups to .analysis-group. Also added new rules for the table
containing the bug information.

* public/v2/app.js:
(App.InteractiveChartComponent._rangesChanged): Added label to range bar objects.
(App.AnalysisTaskRoute):
(App.AnalysisTaskController): Replaced the functionality of App.AnalysisTaskViewModel.
(App.AnalysisTaskController._fetchedManifest): Added.
(App.AnalysisTaskController.actions.associateBug): Added.

* public/v2/chart-pane.css: Renamed .bugs-pane to .analysis-pane.

* public/v2/data.js:
(Measurement.prototype.associateBug): Deleted.

* public/v2/index.html: Renamed .bugs-pane to .analysis-pane and .test-groups to .analysis-group.
Added a table show the bug information. Also hide the chart until chartData is available.

* public/v2/manifest.js:
(App.Model): Added.
