Enable focus ring when 'Full Keyboard Access' is enabled.

For aesthetic reasons the focus ring is disabled as there is no other control that can be active, however this is not the case with full keyboard access enabled as you can tab through the scope bar as well.
Add inactive state coloring for dividers.
Added force open in TextMate and fixed confusion when opening an alias.

Any file should be able to be opened within TextMate, so
Option-DblClick will always do that. I first noticed this with .xib
files.
Because of the order of the if statements, opening an alias to a
package or binary file (or .xib) would not have the previous if
statements applied to it.
Drop other expanded folders when revealing item

We probably should only drop expanded folders which descend from the current root, but that’s more code and the implemented behavior could be seen as “garbage collection” (keeping the memory of expanded folders low).
Handle untitled documents when filtering on path

These would previously be prefixed with the project folder path. Now they get no prefix (and disappear when the path-part of the filter string is non-empty).
Use command name as title for output windows

The command can set a custom title so this is only for commands that doesn’t do that.
Add xib and xsd as XML document types

The former is mainly to allow using Open With from inside TextMate (to force open the document with TextMate), as you likely have Xcode setup as the default app to handle xib files.
Going to SCM status has the groups expanded

Previously these would not initially be expanded but the expansion state remembered. Now that we regularly clear cache of expanded URLs, it’s more tedious regularly having to expand these two groups.

It also introduce new API for having data sources return what items should be initially expanded, which probably makes sense for some data sources.
