Initial attempt at lion restore functionality. Also upgrade sdk to 10.7 and fix a bunch of warnings.

Add 'advanced' setting to profile's directory. Fix bogus NSLog statement in NSBitmapImageRep+CoreImage.m.

Rename Send Input To... to Broadcast Input. Add Use Background Pattern Indicator menu toggle. Fix bug where dimming with broadcast input would behave inconsistently (by allowing broadcasting sessions to be dimmed).

Add sanity check so that TextViewWrapper doesn't treat any subview except a text view as its 'child'

Fix crash on closing a session where a task is freed before routing coprocess I/O. Retain the task in the I/O loop and make sure it hasn't died before trying to do routing. This means that a task's last output may not make it to the coprocess, though.

Change how NSAccessibilitySelectedTextAttribute is handled to fix broken 'speak selection on hot key' in Lion as reported in mailing list on 10/3

Fix 'pate escaping special characters' to include the full range of special characters defined by stringWithEscapedShellCharacters

Change default global key bindings to cmd-shift-arrows to move tab left/right. Add menu item to move tab left/right. Add key action to move tab left/right. Add moveTabAtIndex:toIndex to PSMTabBarControl.

Add support for reporting focus lost/gained (esc[?1004h enables, esc[I is sent by term when focus gained, esc[O when lost, esc[?1004l disables)

Make scrollbars show/hide when exiting/entering lion fullscreen. Also fix bug where tab bar disappeared when exiting lion fullscreen
