Maintain enum order for select options

[adamschwartz]

Maintains the original sort order of an enum for string types which result in the select.html template.

Using an orderBy filter is another option, but I think this is more readable.

Yeah this feels more correct, since the order of an object isn't really a guarantee. I feel we might want to add an "orderBy" option or some such later as well, just so you can override the order in the form definition.

Thanks!

The original enum isn't an object, it's an array, so THAT order can be maintained.

...just sayin :)

@davidlgj Thanks! Note that by default Angular was alphabetically sorting titleMap used in the ng-options, hence how I noticed this in the first place.

@fiddur I believe @davidlgj was referring to titleMap when he said "the order of an object isn't really a guarantee".
