New format for Need descriptions

[aerugo]

People misunderstand Needs and sometimes write long descriptions for a Need, confusing them with Responsibilities.
In fact, Needs should have very short descriptions that should follow the pattern:

We need X (so that Y).

For example:

• We need Noden to be stewarded and led to the benefit of its members.
• We need great online tools to help us coordinate, collaborate, and communicate.

OR

• We need Frihamnstorget and the house to be safe and secure with regards to locks, fire safety, and other matters so that we can work, create, and party safely.
• We need a metal workshop so that we can make metal stuff.

We should implement a UX that makes sure that needs are always short and that helps you format them in this way.
