Separate handling of modifiers from KeyValue class KeyValue defines an ADT and some of its values, it now contains public final fields and no internal logic. KeyModifier handles modifiers and accents and creates new instances of KeyValue when needed. This operation is now properly cached.

Stop using flags for modifiers 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.

Refactor: Separate Events and Keyevents and use enums Negative values for internal events are preventing further refactoring. Add a new kind of key and split internal events (now Event) and Android's key events (now Keyevent). Use enums events and modifiers outside of the KeyValue class. Internally, they are converted to and from integer.

Stop using flags for modifiers 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.
