Macro keys (#878)

Add "macro" keys that behave as if a sequence of keys is typed.

Macro can be added to custom layouts or through the "Add keys to the
keyboard option". The syntax is:

    symbol:key1,key2,..

The symbol cannot contain a : character. 'key1', 'key2', etc.. are:

  - 'String with \' escaping'
    The key will generate the specified string.
  - keyevent:123
    The key will send a keyevent.
  - The name of any special key
