<pre>Summary:
Implement a policy to age-out script/DOM breakpoints. Saved breakpoints that will never be encountered again are wasting space in the WebInspector.Setting. This affects both script and DOM breakpoints, but the latter is slightly worse in that those are all sent individually to the backend when the inspector opens.
Proposal:
Associate each breakpoint with a timestamp that is updated whenever the breakpoint resolves. When breakpoints are loaded, "expired" breakpoints should be removed. A dual policy could also be implemented wherein the breakpoint store has a maximum size, and we trim the oldest breakpoints when we approach the limit.</pre>
