qpointer_adapter class name typo

[fdarling]

I noticed typos in the following file:

sigslot/include/sigslot/adapter/qt.hpp

Line 18 in f8c275d

 struct qpointer_adater { 

qpointer_adater should be qpointer_adapter (it's missing a "p"). It should be an easy fix!

By the way, I haven't yet used the library, but I am impressed with what I've seen so far! I've used a similar library from years ago, and was recently looking for something I could include as a git submodule.

Fixed, thanks.
