Should check if file ends with a new-line and if not add a new line before inserting the recurring entries

[JSpenced]

The todo.txt file should always have a new line at the end of the file. It just happened that for some reason because of some editing I did in an editor that it didn't. This made the first entry not occur on the new line but on the last todo in the list. So I think before adding entries this should check to ensure the file ends with a newline. If not add it before adding the entries to the todo.txt.

eg....

Todo item here(A) entry here from ice_recur

instead of

Todo item here
(A) entry here from ice_recur
