Extend chrome.tabs* API to support multiple tabs.

This adds support for handling multiple tabs, including selecting, removing and moving many tabs at once. (Selecting is now called highlighting for backwards compatibility). The changes are outlined below.

Adds:
- 'highlighted' property to Tab, chrome.tabs.update
- chrome.tabs.query for searching across tabs
- chrome.tabs.highlight for selecting multiple tabs
- chrome.tabs.onHighlightChanged for listening to multi-select events

Modifies:
- renames 'selected' to 'active' on Tab, chrome.tabs.create, chrome.tabs.update
- renames onSelectionChanged to onActiveChanged
- chrome.tabs.move to accept an array of tabs or a single tab
- chrome.tabs.remove to accept an array of tabs or a single tab
- deprecates chrome.tabs.getSelected in favor of chrome.tabs.query
- deprecates chrome.tabs.getAllInWindow in favor of chrome.tabs.query
