Check that AL keywords are not used as variables names, enum values, etc

[KristofKlein]

Not sure if this exists in the normal Cops, but I lately spotted code that had something like this:

enum 234 xx {
 value(0; temporary) {}
 value(1; code) {}
// also nice
 value(13; "begin"){}
 value(14; "end"){}
}

or

var
code: code[20];
Integer: Integer;
Label: Label 'Label';

AL (or other extensions) will hightlight those values as it knows them based on a language context. I think it would be nice, if people that ignore colors, get a small hint, that you should consider a different name/value. Not really an error - but still nice to get awareness.
