Fix #611

Minor but confusing typo in tutorial.
The builder on github is using python 2.5, the views.py testsuite uses the with
statement, and thus flask/testsuite/views.py requires

from __future__ import with_statement

at the beginning.
There was a duplicated call to url_adapter.build(...)

    try:
        rv = url_adapter.build(endpoint, values, method=method,
                               force_external=external)
    except BuildError, error:
        # We need to inject the values again so that the app callback can
        # deal with that sort of stuff.
        values['_external'] = external
        values['_anchor'] = anchor
        values['_method'] = method
        return appctx.app.handle_url_build_error(error, endpoint, values)

   rv = url_adapter.build(endpoint, values, method=method,
                          force_external=external)

If no exception was raised for url_adapter.build(...) then the same method call
would be made after the try...except block. This is unnecessary.

Fix #611
Added support for unicode json dumping.  This fixes #535
Highlight first field on page load, enter sends submit request, double quote to single quote. Submission focuses first field again
Added better error reporting for unicode errors in sessions
missing ' in example

Results in SyntaxError: EOL while scanning string literal
Use sqlite3.Row factory in Flaskr

As pointed out in issue #588 sqlite3.Row should be used instead of
using casting to dict(). Also altered the "Easy Querying" Patterns
example to include the more correct way to return rows as dicts.
Did not touch Tutorial examples ("Views"), as these are not up to
date with the current Flaskr code, and the "Show Entries" section
points out the "Easy Querying" section on how to convert to a
dict().
