Rename BrowserCharm model to just Charm

Rename BrowserCharm model to just Charm

- This is the last bit of unifying the charm models.
- Mechanical change of BrowserCharm to Charm for model/model list.


QA

Try to hit things that load the model. Most things should be a matter of tests
passing, but a quick qa through

- browser
- performing a search
- deploying the charm
- opening the details view from the inspector

LGTM.  Thank you!  Thanks for bringing jcsackett's awesome work to completion. 
Comments from IRC:

<gary_poster> rick_h_, trivial comment, but you could also adjust file names in
this branch if you wanted.  e.g. test_browser_charm_details.js ->
test_charm_details.js.  <shrug>
<rick_h_> gary_poster: sure thing
<gary_poster> rick_h_, though in that case the file name might be intended to be
test browser: charm details.  there is also a test_browser_search_view.js, for
instance
<rick_h_> gary_poster: true, I think some of it is "this is browser code" and
some of it was just naming collisions when there were two models
<gary_poster> so rick_h_ whatever you think
