Made a minor modification to the effect of maria exporting grail's

`find` and `findAll` methods on the maria namespace object.  Also
modified Makefile to ensure these changes are added to the build.

One of the things I like about Maria is that it is helping me get away from JQuery.  Exposing the Grail functions for finding elements allows the user of Maria to use the same interface to find, for instance, sub-elements, as elements.  There may be a reason for not exposing these methods but it seems consistent with exposing, for instance, evento.on, and others.
