Revert "revert desktopgrid realtime gestures port"

Browse source 
This reverts commit ca7fc44814.

Reverting work with no explanation is unacceptable, especially when
you've already been asked to stop multiple times.

CWG has already been contacted regarding this conduct, which is
starting to seem like vandalism of KDE's codebase. I am CCing sysadmins
and officially recommending an emergency recovation of commit access
for uhhadd@gmail.com to prevent further abusive behavior.
