all: implement remote "#get!" and "#put!" with owner and mode

When script with magic command "#get!" or "#put!" executed using "play"
command, one can changes the owner and/or permission mode by setting
the user/group and permission bits after the magic command, for example,

  #get!user:group+0600 src dst

Will changes the owner of dst in local into "user:group" with permission
"0600", while

  #put!user:group+0600 src dst

Will changes the owner of dst in remote into "user:group" with permission
"0600".
