Title: Changed `constraint-error` into `nabl-constraint`. Added warnings for separators on non-list placeholders.

Changed: `constraint-error` into `nabl-constraint` as the old way doesn't work anymore.
Added: Warning for templates such as:

Params.Params = <>

Changing `ID` into `ID*` or `ID+` removes the warning.
