Qt.AlignCenter
Note to Emacs/SLIME users: in order to have them available in code
completion, you need to type them all lower case (not camelCase).
Sorry if this change breaks your current code, but I think this
simplification has been really necessary.

P.S. currently all enums defined with Q_ENUMS, Q_FLAGS are fully
supported; some other ones are still missing, as I need to add them
manually...
