Add two scriptlets: setTimeout-if and setInterval-if

Browse Source 
Usage is similar to that of raf-if introduced in
commit 6831967f5f.

The two new scriptlets are meant to replace:
- setTimeout-defuser
- setTimeout-logger
- setInterval-defuser
- setInterval-logger

setTimeout-logger and setInterval-logger have been
removed, since they are not to be used in production.

To log setTimeout and setInterval usage, respectively
(using aliases):
- ##+js(stif)
- ##+js(siif)

To defuse setTimeout unconditionally:
- ##+js(stif, !)

Usage of setTimeout-defuser and setInterval-defuser
is deprecated and will be removed in some future when
they are no longer in use.

Keep in mind that the new scriptlets function on a
whitelist basis, whereas the deprecated ones
function on a blacklist basis. Prefixing the needle
with `!` allow to use the new scriptlets on a
blacklist basis.
