Fixed
- perf(GoogleDrive): Speed up "no changes" code path
- perf(Folder#clone): Make Folder#clone use prototype inheritance to save ALOT of memory
- perf(BrowserAccount): Don't use browser.bookmarks.getTree() if avoidable
- refactor(isUsingBrowserTabs): Expose Resource#isUsingBrowserTabs
- fix(CachingTreeWrapper): Allow changes to the live tree without disturbing the cache
- fix(App#openInNewTab): Use browser.tabs to open new tab instead of window.open (Didn't work in Edge for Android)
- fix(Default#applyAdditionFailsafe): Only kick in if at least 20 bookmarks are being added
- fix(WebDAV): Add Depth header to PROPFIND for getting filesize
