Changing BundleItemChooser’s hasSelection property now update item names

The items can be named “Do something with «unit» / Selection” and TextMate will show the proper title based on whether or not there is a selection, e.g. “Diff ▸ Document With Clipboard” versus “Diff ▸ Selection With Clipboard”.

Previously though, the item titles were not re-generated when changing the hasSelection property, so the user could be presented with stale titles until some other action triggered re-generation, e.g. indicating that an adaptive item works on current line when there is a selection.
