added mkdir/rm

• added mkdir
• added rm
• echo, cat > file now creates new file if not already exists

Also moved the handling of the output redirection operator to be handled by line_to_args and postcmd.

Now if there is > in the args, stdout goes to the file. postcmd closes the file and sets stdout back to the shell. Much easier that way.

Yeah - it needs #813 which hasn't been merged yet.

Oops - different repository for #813 doesn't autofill. https://github.com/micropython/micropython/pull/813
