Context-Help does not include LANGTYPE enum

[pryrt]

It would be nice for the help file to include the LANGTYPE enum in the Enums section, and add the links there from the getCurrentLang() and getLangType() mentions of LANGTYPE.

See #94 and https://github.com/bruderstein/PythonScript/blob/master/docs/source/enums.rst#langtype -> will be part of next release.
