fix(block): Remove support for nodeAttrs[this]

This code is no longer needed since directives
now have mappings which can be used for the same
thing.

Closes #87
chore(parser): Fix up library name and export from Angular
fix(Zone): dump zone errors into karma console.
feat(block): Support {{}} in attributes mapping to components

Closes #85

A directive/component can now use map @attribute, and
that attribute can now contain {{}}.

BREAKING CHANGE: only transcluded elements can now
contain '.' in the map annotation.
