Add support for IEC 61131-3 Structured Text

[bdorninger]

Structured Text is a widely used language in the domain of process automation. It is standardized in IEC 61131-3. However, there are quite a lot vendor specific dialects.

Github classifies the *st files as Smalltalk. There is currently no support at all for this language, so that detection cannot be overriden
