Allow changing trace file in the example trace_viewer.

A select box is added to the example trace viewer that allows
the selection of the displayed trace at runtime. This makes it
easier to see various types of trace files as needed.

r300 switched the way slices with two titles were analyzed. The test just wasnt
updated.

Add history support to the analysis view.

Currently if the back button is used we'll lose your trace data
as chrome navigates back to before chrome://tracing was accessed.

With this CL, we will push the current selection onto an internal
array which will be used to restore the previous selection if
you use the back button. If you make a new selection, it is also
possible to navigate back to the previous selection.

Selections are not highlighted in the timeline view as you navigate
through the history.

This will use more memory as we will hold onto each selection as
you navigate.

Fix loading of non-JSON data files.

When loading trace files we need to make sure that the data is
actually JSON before attempting to parse. If the data isn't
JSON, e.g. Android systrace or v8 log files, we provide the raw
string as the trace events and the importers will do the right
thing.

Add test for loading of trace files.

This adds two simple tests to verify that sending JSON parsable
data through to loadTraceFileComplete will work and also that
sending non-JSON parsable data through will also output the
intended results.

Move guid and settings to base.

The Settings class already had an exportTo of 'base' so it was
just in the wrong folder. I moved the GUID class as it has
nothing, directly, to do with tracing and is more core functionality.

Add parsing of implicit objects

A snapshot whose args has itself an object with word "id" in it it
is assumed to be a snapshot of another object. Recognize that object and
build an instance for it. We use this to recognize tiles in detailed tile
manager dumps.

When x: {id_ref: 0x1000} is found in as an argument in any item the model, look up the

the timestamp of the item. If matched, replace the {id_ref: ...} wtih the
found snapshot.
