Update makefile template and css build targets.

Update makefile template and css build targets.

- The template targets didn't take into account the subapps directory.
- There was no direct target watching css files. Since they're built as part
of the templates I think it's typical for a template change to accompany css
changes and it wasn't noticed there was a corner case.

To QA you need to run `make build-prod`. Once that is done, run it again and
see that it does not rerun any builders on the template/css targets.

Then, touch a template in the subapps directory and make build-prod again.

`touch app/subapps/browser/templates/minimized.handlebars && make build-prod`

Run build-prod again and see that there's no change. Then touch a less file
and verify the makefile catches it as changed and rebuilds.

`touch lib/views/browser/charm-token.less && make build-prod`

Nice.  I had one small regex suggestion.

File Makefile (right):

https://codereview.appspot.com/10756043/diff/1/Makefile#newcode125
Makefile:125: TEMPLATE_TARGETS=$(shell find app -type f -regextype
posix-extended -regex '.*(handlebars|partial)')
I would tweak the regex to be ".+\.((handlebars|partial)" so files like
"dentures-partial" won't match.
