Remove new_qenv (#222)

# Pull Request

As commented on #215, it was hard to see a pattern on what to do when
deprecating functions.
Based on @m7pr feedback I deleted the help page and the code (generic and methods).
teal.gallery and tlg-catalog were searched and no usage was found (and deprectae_warn, would have warned). 

Fixes #215

 ### Breaking Change
 
-* `qenv` objects should now be created with `qenv()` rather than `new_qenv()`. The new constructor always creates an empty object. `new_qenv` is now deprecated.
