This adds a new flag, allowing the user to define global shortcuts that trigger input events within the main window.
That way, I could easily wrap SoundCloud and Deezer to create a native app which reacts on my keyboard media buttons.
When the `getCurrentUrl` function was refactored to make use of the `withFocusedWindow` function in ac99c6424d, it stopped returning a value and broke the "Copy Current URL" feature (#633).
This change restores the original behavior of the getCurrentURL function and makes the "Copy Current URL" feature functional again.
Most Unix-based command line utilities respond to a _lowercase_ `-v` flag which outputs the current version. Adding that as an alias here in addition to the already present `--version` and `-V` flags :)
When using an app such as Gmail, the unread count is included in the title, and the --counter feature displays that number on the dock icon. However, when the number is larger than 999, it includes commas in the number (e.g. "1,000"), and the number is no longer displayed on the dock icon, because the regular expression used to detect the counter value does not permit punctuation. This change modifies the regular expression used to match the counter value to permit "." and ",".
* 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.
