Add keyboard modifiers to input event

Browse Source 
Making applications track modifier keys results in unnecessary work for
consumers, it's error prone, and it turns out to have unavoidable bugs.
For example, alt-tabbing with x11 results in the alt modifier state
getting stuck.

To resolve these problems, this patch adds a Mods value to the keyboard
input event.
