#6771: Move wrapper function into __init__ and eliminate wrapper module

Andrew agreed in the issue that eliminating the module file made sense.
Wrapper has only been exposed as a function, and so there is no (easy)
way to access the wrapper module, which in any case only had the one
function in it.  Since __init__ already contains a couple wrapper
functions, it seems to make sense to just move wrapper there instead of
importing it from a single function module.

+- Issue #6771: moved the curses.wrapper function from the single-function
