The ability to search in multiple address books or even the whole address books space would be fairly helpful for users. Sometimes if we don't know which address book we have put a person's address in, it is a pain to search the address books one by one.

This patch ports the relevant parts of the following bugs to SeaMonkey:

• Bug 170270 - Enable search in multiple/all address books
• Bug 1140768 - Fix typo of "gShowAbColumnInComposeSidbar" in abContactsPanel.js and improve the logic of hiding the "addressbook" column
• Bug 1143812 - Always allow creating new contacts and lists after opening addressbook by using Personal Addressbook when a usable AB is not selected
• Bug 1142705 - Contacts sidebar doesn't remember the last selected address book after Bug 170270 checked in
• Bug 824150 - Code cleanup in /mail/ and /mailnews/
• Bug 691141 - rework AB contact photo storing UI
• Bug 1319409 - Rename GetSelectedDirectory() function to getSelectedDirURI(), and various related code cleanup/refactoring
