Continued Craziness

There were continued issues with scoping after the last release -- with help from @rainboxx they should be resolved.

Controller Quirkiness

The way in which the transcluded content was not being added to the DOM after transclusion was causing all kinds of issues during linking. Now the content is added to the DOM in a hidden node, and then moved from that node to the correct place during link.

Default block content.

Clear blocks when transcluding to allow for default content; thanks @littlemtravis!

Refactorcism.

A pretty significant refactor to clean up the code; thanks @dlongley!

Bug fix.

Fixes a pretty egregious memory leak.

First release.

First release of ng-multi-transclude; seems to work pretty ok but has known issues with nested transclusions (see #8).
