Clean visual style, part II: extend bright style, convert icons, more touch-ups.

This commit removes the remaining white icons from the previous style,
which was a mix of 'holo dark' (i.e. light) icons and other un-fitting
icons. It's all replaced with theme-colored icons.

The primary color itself had been altered a bit towards green (#18aba1).
Other than the icon replacements, this commit changes:
 - tab switcher: fix cosmetic bug in the title bar in <= xhdpi devices
 - tab switcher: better incognito presentation
 - settings: enable back (<-) arrow
 - settings: bold color in the activity (on L and up)
 - settings: rationalized launching
 - better spacings on the mobile title bar
 - better padding on history items
 - add proportional padding (1em) to the incognito page
 - the incognito tab bar gets a bit darker
 - ['Ingnito Page', 'New Incognito Tab'] -> 'Private Browsing'
 - 'Page info' -> 'Page information' (no abbrevs when user facing :)

Vast amount of unused resources are removed from the APK.
