Fixed: warning notification said "Error parsing…" instead of "Warning parsing…"

I was missing the variable in a test.
Fixed: XcodeCapp would attempt to open a path that did not exist or was not a directory.

The first defense against this is to validate the recent menu items to ensure they exist and are directories. If not, the item is disabled.

The next time a project is opened, the missing project is pruned from the recent menu.

The second defense is a check when an attempt is made to open a project.
