input-emulator v0.4

Changes since v0.3:

• Make sure commands are performed synchronously

  When scripting commands, request messages would pile up and overflow the
  message queue resulting in crash or errors. To avoid this we now wait
  for each command to finish (wait for ok response) before firing the next
  command.

• Fix stop command crash

• Wait for service to be fully initialized before exit

  To prevent command-line client from making request before service is
  fully initialized.

• Make sure only one client is talking to server at a time

• Update kbd example

• Update README

• Remove lua script code

  Can be reintroduced if needed. For now everything is perfectly
  scriptable via command-line commands.

• Add 'mouse scroll ' command

• Add bash completion script

• Add alias_to_key() and more aliases

• Move code to keyboard
