Release Alicia-1.1.4

Fixes:

• Fixed '?' command
  
• Fixed bug in the case that 'class' command was called without args.
  

Features:

• Alicia::GDB::Macro was released. This feature makes it possible to
  use GDB macros in Alicia namespace during gdb mode.
  
  package MyMacro;
  use base qw(Alicia::GDB::Macro);
  sub new { shift->SUPER::new(filehandle=>\*DATA); }
  1;
  __DATA__
  define inittask
  set $init_t=&init_task
  set $task = (struct task_struct *)$init_t
  printf "pid: %d, comm: %s\n", $task.pid, $task.comm
  end
  
  alicia> load 'MyMacro.pm'
  alicia> print MyMacro->new->inittask
  pid: 0, comm: swapper
  
  
• KStruct.pm was imported into Alicia::KStruct and Alicia::GDB::KStruct
  allows you to use KStruct feature in GDB mode.
  KStruct.pm was deleted so that "use KStrcut" has to be removed from
  your script.

• 'helper' command to help for your new ldas was added.
  alicia> helper 'My::Command'
  alicia> !vi My/Command.pm # Add your feature
  alicia> reload 'My/Command.pm' # if you added
