Alias ls and dir commands inside new SMB session type prompt

[cgranleese-r7]

This PR adds support for aliasing the ls and dir commands. In aims to improve workflows for those who have windows muscle-memory.

I also spotted an issue when running the ls -h command which return an error:

SMB (192.168.175.193\my_share) > ls -h
[-] Error running command ls: NameError undefined local variable or method `cmd_ls_help' for #<Rex::Post::SMB::Ui::Console::CommandDispatcher::Shares:0x00007fbb9e12d750 @shell=#
...
Did you mean?  cmd_bg_help
               cmd_cd_help
               cmd_help
               cmd_pry_help
               cmd_irb_help
               cmd_cat_help
               cmd_pwd_help
               cmd_help_help

So I added what I believed was required and tested it and it seems to now be working as intended.

Verification

List the steps needed to make sure this thing works

• Start msfconsole
• Get a SMB session via the smb_login module
• Use a share via the following command: shares -i <share name here>
• Verify the dir and ls commands now both work
• Verify the dir -h and ls -h commands now both work
• Verify the help dir and help ls commands now both work
• Verify the tab completion for both dir and ls works as expected
