Subject: [PATCH] Avoiding todo.sh help error when .todo.actions.d contains
 subdirs.

I have placed tests for my custom todo actions in ~/.todo.actions.d/tests/; this causes a ".../.todo.actions.d/tests: is a directory" error on todo.sh help.
Added condition for regular files to the executable check in order to exclude subdirectories.
