There was no free bits left to add new modifiers. Instead of increasing the width of the 'flags' field, refactor the way modifiers are represented and used. Modifers are now represented as independent values and stored in the 'code' field. A flag is added to distinguish between modifiers and keys with a key event. The most notable change is that modifiers can no longer be or-ed into a single value but have to be represented as an array.
