tabbrowser: implement method getTabForBrowser() like Firefox
Versions affected: SeaMonkey 2.36a1-2.39a1 trunk Extensions affected: Ghostery, Drag-Select Link Text and others. sdk/page-mod is not loading content scripts, the page is not being affected by the script and the script does not appear in the remote debugger. Attaching to existing pages results in error: "tabbrowser.getTabForBrowser is not a function" Excluding "attachTo" does not produce an error message but still the script is not loaded.
This was working in 2.32-2.35a2 so marking as a regression.
