Target create form should require Description

[wyrzykow]

In the Target Create form (after Catalog Search or after simple Target/Create), there is the field Description. It should be mandatory and it should require at least 10 characters. The description of the Description field should say: "Target description, mandatory, min 10 characters, for example: candidate supernova, or: old target, do not observe."

we should also make this mandatory in the Import, but I don't know yet how to request this.
