Auto-discovery removal

Given #312, auto-discovery was actually proved useless, and thus it was removed, together with the files it had shown as useless.

morphTo() fix and auto-discovery

Brings in changes from PRs #305 and #310, a new maintainer to try to help out and maybe some space for other fixes.

v3.4.2: Leaving glocal scopes to be applied by Eloquent

Closes #245 and finally fixes #281
  newQuery() is used to both create a Builder and apply scopes. This was being
overridden so we could use our own Builder, but it brings more tasks inside
the same overridden method. Thus, we now override newQueryWithoutScopes()
that is indeed the main builder-instantiator, and leave scopes for Eloquent.

v3.4.1

fixing dead reference to old `$externalValidator`

Unique rules can now be safely used outside of the model

You can now use $model->buildUniqueExclusionRules() in your FormRequest::rules() for additional validation awesomeness.

HasManyThrough::localKey and unique rules for new models fixed

• [enh] added support for HasManyThrough::localKey
• [bug] unique rules were being built with an empty ID clause when used for new models

Fixes memory issue (infinite loop) on plain find() calls

The issue is explained in #283. Thanks @paul-crashley :)

Save safely with unique rules

From this version on, the save() method will always fix the unique rules (include the model ID on them) before validating.

Marking this version as stable since I'm using it for some weeks on Laravel 5 and found no upgrade issue.
