Move to working fork of ncurses wrapper

[Patasuss]

The original version has an out of date .nimble file which does not work with the current version of nimble.
See this issue in the original repo. Someone made a PR with a fix, but the maintainer seems inactive.

I forked the repo, fixed the .nimble file and corrected a compiler error within ncurses.nim.

Someone made a PR with a fix, but the maintainer seems inactive.

I'm surprised to see that the changes in that PR are needed, because the existing version seems to follow what is written here: https://github.com/nim-lang/nimble#creating-packages

@genotrance @dom96 any idea why the original package and its .nimble file doesn't work? Is the problem in name parameter?

This is the error log I get:

Nimble files have never supported the name field - it has been called packageName for at least 5 years and is not required since it is derived from the name of the nimble file.

Are there any problems with this PR that I should know of? It's just sitting here, inactive.
