Rework MustacheContext (#64)

Introduce `mirrors.dart` and make use of it for creating mirrors. This should make dart2js work a little bit better. As a side effect of the reworks dropped support of invoking methods starting with `get`.

+As part of the [MustacheContext rework][pr-64], a couple of simplifications have been made. Most
+notable one is the drop support of mirroring methods starting with `get` as it does not make any
+sense with dart. Use a getter instead.
