Resolved a build error in MainMenu.xib from a git pull.

Two objects had the same ID. The fix changes one of the IDs.
Removed old .xcodeproj/project.xcwordspace/xcuserdata folder.

This has been ignored from version control, but never removed.
Updated About Liasis page with new website.

Includes minor layout refresh.
Improved method for determining completions in PLInterpreterController.

In the textView:completions:forPartialWordRange:indexofSelectedItem: method of PLInterpreterController, use the arrayByEnumeratingPythonSequence:withBlock: to retrieve all items in the module dict keys.
PLTextEditorView now uses a theme-aware color for its column ruler.

The subclass now observes changes in the theme manager. On change, it sets the column ruler color to a blend between the foreground and background.
The PLFormatter method indentationLocationOfLines:inRange: no longer throws an out-of-bounds exception.

This exception will be thrown by Cocoa methods used internally.
