<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/196971">r196971</a> - Some timer alignment cleanup.
https://bugs.webkit.org/show_bug.cgi?id=154559

Reviewed by Chris Dumez.

Document shouldn't override Page's timer alignment policy with a lower alignment,
and m_domTimerAlignmentInterval isn't really a Settings, it's just the current state
for the page.

* dom/Document.cpp:
(WebCore::Document::timerAlignmentInterval):
    - take the max of the possible intervals.
* page/Page.cpp:
(WebCore::Page::Page):
(WebCore::Page::setTimerThrottlingEnabled):
(WebCore::Page::setDOMTimerAlignmentInterval):
    - moved here from Settings.
* page/Page.h:
(WebCore::Page::domTimerAlignmentInterval):
    - moved here from Settings.
* page/Settings.cpp:
(WebCore::Settings::setDOMTimerAlignmentInterval): Deleted.
    - moved to Page.
* page/Settings.h:
