Remove @if and @idx

[jimmyhchan]

closes #95. Following up with #102 where the idx and the if helpers were deprecated, this pull request finally removes these helpers.

With all the other helpers coming in, if is just unnecessary. This is breaks back compat so a 1.6.X branch is desirable.

You have some weird commits in the PR, squash?

Is there anything else we should do before cutting a 1.6? At a minimum I'd like to get #108, #109 in.

Also, there's no dustjs 2.6 yet, so we can't actually cut a 1.6.

So I've been doing upstream tracking wrong this whole time... derp. Fixed now.

I don't know how best to announce this change. It's pretty major and i doubt anyone is going to RTFM before they update. The deprecation warnings are there but logging is off by default.

It's made easier by the fact that no version of Dust exists that supports
1.6 yet anyways so we can tell people twice :P

Throw the deprecation warning in the github wiki for now. This lgtm, will pull in when Seth or anyone else gives the go ahead.

Squash looks good; don't pull it in though until we're ready to cut a 1.6. If you pull it in now we can't release a 1.5.x without cherrypicking.

I love how this breaking change came out in a minor version bump.

[sethkinast]

As has always been the case, Dust versioning follows different semantics than semver (this likely will change for Dust@3)

Minor versions of Dust can change or remove functionality after deprecating the functionality for one full minor release. Patch releases of Dust and helpers always maintain compatibility. We recommend using ~ versioning, not ^ versioning, for Dust's entry in your package.json.

These two helpers were present in helpers 1.4.0, deprecated (with messages) in 1.5.0, and removed in 1.6.0.
