Normalized Browser Link
Removed '/u/1/' from browser links like mail.google.com/mail/u/1/#inbox. Keep in mind to log into the account first. Use 'Edit > Copy Mailplane Link' if you want the originating account embedded in the link.
Standardized Status Bar Item
Status bar item supports dark mode (OSX Yosemite) and it doesn't turn red anymore if unread messages are available. This makes it a better fit for the status bar.
