Bug Description

See initial report on barajas project:
https://bugs.launchpad.net/barajas/+bug/1376165

Basically we should free the resources of open tabs when they move to the background during the running of the browser as each tab uses much memory and cause the system with low memory, especially on krillin, to start killing everything with the oom killer.

See the details in the barajas report.

We should keep at most the last two tabs in memory and free all the rest. Even if this means losing the screenshots of the open tabs, it's better than blowing out memory. When a new tab is requested, the old tabs should freed and we just save the url and display like we do when starting the browser up and not instantiating all the tabs.

in addition to freeing up tabs when they go to the background, maybe we should change the default behavior when invoking the browser externally to not open in new tabs but open in the current tab. This has the advantage of low overhead and maintains the navigation history in the tab. When we start killing off tabs we loose the navigation history for that tab as well..

That will be addressed when bug #1353143 is fixed.
