Reduce `yas-new-snippet-default'
* yasnippet.el (yas-new-snippet-default): Remove
"require-final-newline: nil", it's redundant since `snippet-mode' already
sets that. Also remove the direct-keybinding, since it's hardly ever
used, and often the literal "# binding: direct-keybinding" ends up in
actual snippets.

Don't use yas-x-prompt by default
It is not a very pleasant method when there are many values, and
`yas-completing-prompt' will usually do a better job, in addition to
respecting customizations to `completing-read-function'.
`yas-dropdown-prompt' remains in first place, since it only takes effect
if the `dropdown' library is loaded, which likely indicates a preference
for it.

Slightly improve on fix for #515: Refactor code and add tests
While I agree with the solution for #515 in commit 17fe790 for now,
other approaches might be interesting in the future, like clearing on
other types of insertion, not just self-insertion.
So add some tests and refactor a new function that could be used for
that purpose later on. For now, change no behaviour.

Respect y-b-l-cond from binding triggered snippets
