Bump version number

This is a hotfix for fixing compatibility problems with PyQt 4.7.
Fix for PyQt 4.7

Older versions of Qt do not have the swap() method for QKeySequence
objects, so they must be re-instantiated instead.
Release of v1.1.1 (hotfix)

Fixes QKeySequence manipulation with PyQt4.7.

(Merge branch 'pre/v1.1.1' into stable)
