Web Inspector: Allow SplitView to keep the sidebar size as a fraction of the container size
https://bugs.webkit.org/show_bug.cgi?id=109414

Patch by Vladislav Kaznacheev <kaznacheev@chromium.org> on 2013-02-11
Reviewed by Vsevolod Vlasov.

SplitView now interprets defaultSidebarWidth and defaultSidebarHeight values between 0 and 1 as
fractions of the total container size. The sidebar then will grow or shrink along with the container.
When the sidebar is resized manually the updated ratio is stored in the settings.
