more special chars in tags/project names allowed

[tolry]

taskwarrior allows special chars as @, _ or - in tags and project names, not sure if this list is complete, should I investigate a bit more?

It's okay. But can you update some tests?

And are you sure that you can use - in tags?? I have a negativ test for it, but i don't know why :D

@DavidBadura - might be a problem in tags, haven't used it there yet, I will have a look and check TW docs/code in parallel to make sure
