Closes #35

Actually i regret a bit of introducing taskchampion. It is really cool in order to ensure some kind of better interaction, but the problem is, that taskwarrior and taskchampion are not consistent in the validation.

taskwarrior is sometimes something interpreting which does not make sense, but supports command in order to set various fields automatically and validating and translating e.g. due timestamps, while taskchampion focus on storage and requires already valid data, but it does not check for consistency.

Not happy on.

Hm, for now what we can do is, when there are entries in additional options, use task warrior command, otherwise use taskchampion. That way we keep both. I know, it is an ugly hack, but it gets the thing done

Actually this is not as easy and will bring new side effects. This is the reason, why i've made manual support for now on the corresponding most features. With this we get some time to think about it.
