* Fix sites that use about:blank redirect technique
When you open some links with Google Calendar, instead of opening the link directly, the site opens a new window with the location 'about:blank' and then sets the new window's document content to include a refresh directive to open the actual link. This change causes the 'about:blank' links to be handled internally so that the technique can actually work.
* Hide 'about:blank' windows while they perform the redirect
After a new window is created for an 'about:blank' link, the redirect occurs, which causes another window to be opened. This change causes the 'about:blank' to be created hidden, and then closed entirely once the redirect finishes.
* Add tests for `linkIsInternal`
* Refactor onNewWindow to make it testable
The tab feature introduced by #579 included a change that checks the `disposition` parameter and conditionally creates tabs, and that check was placed prior to the check to see if the URL is internal. This change moves the `linkIsInternal()` check earlier so that external links are always opened externally, regardless of disposition.
As part of #591, all window creation was routed through a createNewWindow function. That change introduced the regression reported in #616 in which popup windows could not communicate with their parent windows. This change reverts that behavior for windows opened via JavaScript (that aren't being opened as tabs and aren't being opened in external browsers), thereby fixing the reported regression.
By changing incorrect window `guest` property to `newGuest`. See

Electron supports using native tabs on macOS (API added in Electron 1.8.1). This change adds a context menu item on platforms that support it (macOS for now) to open links in new tabs, and also adds support for {command,middle}-clicking links to open them in a new tab.
Maintainer (@ronjouch) note: this feature is macOS-only. Windows/Linux patches welcome 🙂.
The electron-context-menu package uses the context-menu event emitted by WebContents (API added in Electron 1.0.2) to add a general context menu supporting generic actions (e.g. cut/copy/paste) that can be customized. This change replaces the existing context menu, which relies on adding an event listener in preload.js, with one built using the new package.
