Add template library resources as needed

[awiner, 2009-05-28 23:43:23]

This takes the unchecked-in-parts of http://codereview.appspot.com/53052 and
modifies/simplifies them further.  In particular, template library scripts and
styles will only be registered when the relevant library or tag in the library
is used.

Also, the NameTagHandler code (now unused) is deleted.

Missing functionality: template library injection for client-side processing is
too large (re-includes script and styles unnecessarily, even if they were used
already on the server).

Generally awesome. One config nit.

from container config rather than hardcoded? See line 161 below.

Doesn't look like theres a test for these occlusion rules.

Line 162: libraries.add(osmlLibrary);
this should be coming from container config.
