Add CurrentDate function

When we're in a file with a filename whose root (prior to the extension)
is in YYYY-mm-dd form, return that date. Otherwise return the current
date.

Updates the <leader>cd mapping to insert this text instead of the
current date.

This is useful for vimwiki journal (diary) entry headings.
