[development] Formapi formalter

[Karthik]

> The plan was, to use taxonomy (free tagging) to collect "cities", "keywords",
> "countries" etc. Taxonomy is very usefull for that, but it comes in a
> collapsible form (ugh) all grouped.
> Form alter to the rescue. Just flatten the array (pull the taxonomy out of the
> collapsible) and change the weights, so that we could place them whereever we
> wanted them.
> The form looks great, then. Looks. But it is altered, and threfore does not
> behave the way it did. Taxonomy now does not know about any of the filled
> terms anymore, and simply ignores them: taxonomy terms are not saved to the
> database.
