Fix Alt Graph Mappings not being applied

[kittsville]

Mappings for IPA characters ɦ (keycode 85, normally 'u') and ɚ (keycode 222, normally '@') are not working and the default values are being used. I would presume this is the case for other mappings.

While ɦ is defaulting to to its regular value ú, ɚ is not being typed at all. There may be multiple issues occuring.

I have checked the layout file of both and they have the correct characters.

Bug was introduced in a132eb6 by causing the Ctrl key to force default behaviour. While this allowed for browser controls it broke all Alt Graph mappings because Alt Graph (right Alt) is equivalent to and treated as Ctrl + left Alt.

Adding a check for the Alt key as well as the Ctrl key solves this, as if the Alt key is pressed then the key should not default to defaulting.

While some keyboard shortcuts start with Ctrl + Alt, I cannot think of any that the OS wouldn't do regardless of what my little web app wanted.
