Change chrome://crash (sad tab page) "Learn more" link to:
"If you're seeing this frequently, try these suggestions."
Link "these suggestions" to the "Learn more" help article.

Update Views, GTK, and Cocoa implementations.
chrome://kill (unused) changes on Mac, but not on Views nor GTK.
Not wrapping this line on overflow for Views and GTK seems acceptable.

Strings: Add sad tab help message and embedded link resources.
Views: Rewrite the SadTabView to use ImageView, GridLayout, etc.
GTK: Add new prefix and suffix Label Widgets to an hbox with the link.
Cocoa Support: Create HyperlinkTextView for non-selectable text & link.
Cocoa IB: Replace SadTab.xib NSButton with a NSTextfield placeholder.
Cocoa: Replace the placeholder with a customized HyperlinkTextView.

BUG=80428
TEST=chrome://crash and chrome://kill on all platforms.
