Move Scripts menu to left of Window menu.

The Xcode menu bar now ends with Window then Help, like other OS X apps.
Don't load fixins when it's opendiff rather than Xcode that's loading.

This is to cut down on terminal output when using opendiff from the
terminal via git difftool.

(It's open to debate whether this is the best thing to do. Other options
might be cutting down on the NSLog calls, only logging if isatty(stderr),
etc.)
Stop fixins loading when it isn't Xcode that's loading.

...and hopefully the Xcode process name will continue to be "Xcode"
across versions.
Fix some Xcode 4.4 format string warnings.
Set XCFixin_UserScripts' principal class, so that Xcode 4.4 will load it.
DisableAnimations fixin will now disable the manual code completion popup animation
Tab key will accept the current completion instead of just accepting the first matching prefix
Merge pull request #6 from tumult/master

Disable code completion popup animation
Replace NSLog with NSAlerts for the cases that actually happen.

The NSLogs are still there, just disabled. Maybe add in runtime switch or
something.
Add "line" and "linetext" stdin modes, and some more logging.
- general housekeeping
- updated readme, added section for TabAcceptsCompletion fixin.
- removed DisableWriteStateData fixin, since I don't use it any more (and I doubt anyone else does either)
- removed OptionClickDocumentation fixin since it broke with Xcode 4.5 (may re-implement it eventually)
- added check to XCFixin.m to prevent fixins from loading in Xcode versions < 3, which was apparently possible (and they end up crashing Xcode)
