Breaking change in v0.5.1 when using Concat on Windows

[HNygard]

Today I've tried to update grunt-angular-templates from 0.3.10 to 0.5.5. The build failed and I traced the error back to the changes happening in v0.5.1.

I've noticed the comment by @mzgol on 7cdbd768d8b6f1f15a7d93bb458ce32a17af867d:

This doesn't just add the usemin option, this removes the concat option as well. This is a breaking change, you should have changed the version number to 0.6.0, patch releases shouldn't introduce breaking changes... I've just got bitten by that.

Was concat support removed?

Running build on Windows 7. It's running in "Git bash" (cmd with bash).

Which generator are you using for your project? I'm trying to figure out how to best test this...

@ericclemmons : Generator? The config for grunt-angular-templates was manually created. The htmlmin part is untested (going to test and tweak it tomorrow).
