bstart building challenges
challenges: fix up lists to use new list templates
challenges: list taken dynamically from scope so we can push/unshift to various task lists depending on location of add-task form. be careful with this commit, not the {{}} instead of {} - seems to be required otherwise things get weird
challenges: add assignTo option on challenge-creation
challneges: semi-functional challenge creation for parties
challenges: basics for challenge subscription
challenges: chevron in collapsing title
challenges: add challenge.id to task so we can get the icon-bullhorn
challenges: prevent some task options (such as scoring, check-marking,
tags, etc) for challenge edits
