Implement client-side incognito mode

Since WebView deprecated privateBrowsing in API 17 (and killed it
for good in API 19), we were left without incognito in the Browser
app. Follow the docs' recommendations and implement it with "manual"
control of privacy-related engine options

* Internally track incognito state for tabs
* Disable all forms of storage and cache on private webviews
* Disable all cookie activity while an incognito tab is active
* Stop trying to use the deprecated "privateBrowsing" argument
  when creating webViews, always set to false

BrowserSettings: update desktop UA string to match Chrome 30

Now that we're using a Chromium-based WebView which closely matches
Chrome 30, we should report as a newer Chrome version when masquerading
as a desktop browser.

Replace removed NARROW_COLUMNS layout mode with TEXT_AUTOSIZING

For reasons which I completely fail to understand, Google elected not to
implement the very useful NARROW_COLUMNS layout mode (double-tap to
reflow text) in Chromium WebView, and instead chose to implement
TEXT_AUTOSIZING (buggy heuristic-based font inflation).  But complaining
isn't going to get it back, and font inflation is better than nothing on
small screens, so replace NARROW_COLUMNS with TEXT_AUTOSIZING to restore
some support for resizing text to be legible on screen.
