add base css class to {{flash-message}}

[kellyselden]

I'm not using bootstrap or foundation. It would be nice to have a more specific way of selecting than: <div id="ember1749" class="ember-view alert alert-info active"> so it doesn't collide with other potential selectors. I propose "flash-message" so it would be <div id="ember1749" class="ember-view flash-message alert alert-info active">. I would be open to doing the PR if it's approved.

I mean it's not too hard to do {{flash-message class="flash-message" flash=flash}}, just curious if you wanted it default.

Sure!

@poteto I ran across this and thought I'd knock this out. It's a one-liner if you don't care about tests. Do you want me to specifically test this or no?

[kellyselden]

@jfelchner I would test for it, since if it were to be removed accidentally and people started using it, it would be a bug. On the other hand, I am a bit of an extreme tester.

Great idea - looking forward to this feature
