Text fix

We found an existing Project directory: $1.

We are renaming this to $1.old.

(If that directory already exists, we'll add another ".old" to that one,

and so on, and so on, and ....

and so on, and so on, and ....)

		my $old_project_path = "$basecalls_path/$1";

		directory_rename($old_project_path);
