Removed SDF naming annotations.
Removed generated and unnecessary files and added a .gitignore for SDF.
Added warning for Cons as constructor name as well.
Added simple sort name binding for template language. Disabled all NaBL errors since sorts can also be defined in SDF files, which are not considered in name analysis yet. Reference resolution and completions work if the sort is defined in the template language.
Removed some generated and unnecessary files and added a .gitignore for template language.
