Use a dynamic method to print events to stdout

Add a flexible helper function print_event() and use it whenever we
print events to stdout. This reduces the number of copy-pasted code and
eventually allows for specifying custom format strings.

Following format specifiers are supported:

* m: Print the description of the item
* n: Print the name of the note file belonging to the item
