MicroStateMachine::input() returns whether a result was set now

 * this means that QRegSpecMachine::input() no longer has to return
   a dummy QRegister in parse-only mode.
   This saves an unnecessary QRegister table lookup and speeds up
   parsing.
 * QRegSpecMachine can now be easily extended to behave differently
   when returning a Q-Register, e.g. simply returning NULL if a register
   does not exist, or returning a register by prefix.
   This is important for some planned commands.
 * StateExpectQReg::got_register() now gets a QRegister *.
   It can theoretically be NULL - still we don't have to check
   for NULL in most cases since NULL is only passed in parse-only mode.
