Introducing _clientdeleteonly property for Store plugin

Sometimes we need to delete annotations just from the client side and we do not want our system to delete the
annotation from the backend. However the store plugin listened to the annotationDeleted event and automatically
deleted the annotation from the backend. Now, annotations can be tagged with the _clientdeleteonly property in
which case the store plugin only unregisters the annotation and does not trigger a delete to the backend.

Match mouseup on the whole document.

You can always select so that you go away from the area where you started, away from wrapper and then there release the mouse. It would be more reasonable to limit mousedown event, but not mouseup.
Merge pull request #27 from peerlibrary/document-mouseup

Match mouseup on the whole document. (Helps when user moves the mouse out of the wrapper before releasing the mouse)
