directive html files are not getting built by grunt, and therefore none of the items or solutions can render in deployed client's expert UI

1. Go to http://test.doozer.tips/#/solution
   Expected: see the list of all solutions and all the items
   Actual: none of the solutions or items render

there's a console error - the html files for the directives to render items & solutions aren't getting built correctly. grunt build minifies the directive js files, so they’re included, but .html in the directives folder isn't.

Error: [$compile:tpload] Failed to load template: scripts/directives/dzr-solution.html (HTTP status: 404 Not Found)

also none of the favicon files are getting built / included correctly either... (might need a separate bug, but keeping together for now - they might have a similar fix...)

OK here's the answer! https://stackoverflow.com/questions/18577540/adding-partials-to-grunt-build-when-building-an-angularjs-app

need to add the right paths to Gruntfile.js so it knows to look at the directives folder for html files too...

i think the same applies to the favicons, but looking at that next...

i'm going to reopen this because i have no way of testing my fix... i believe that commit should do it, but @joebasirico - can you please code-review my checkin & try the grunt build process again to see if this is the right fix?
We can close this bug again, once we've verified the build & deploy works correctly.

Note: I made 2 changes to the Gruntfile.js, to fix 2 related issues:

1. (line 339) htmlmin function - added 'scripts/directives/{,/}.html' to the src paths it looks for files. i believe this should fix it to find the directive html files in their current location.
2. (lines 374 & 379) copy function - adding the locations of the favicons and related files so that grunt copies them over (this includes the icons folder - 'icons/{,/}.{png,ico,json}' - and the browserconfig.xml file which should be covered by adding xml to this line - '*.{ico,png,txt,xml}')
