The 'translate' esh plugin
------------------------------------------------------
translate is a builtin command that lets you translate
text between two languages and detect what language 
your text is in
usage:

translate or translate -h
	will display help information

translate [LANG_CODE] [INPUT]
	will translate input according to LANG_CODE

translate -l
	displays all supported LANG_CODEs

translate -d [INPUT]
	will output which language the input is in

Example: "translate en-de hello world"
	Hallo Welt

NOTE: If you get a segfault while running this plugin,
it is most likely because you do not check if the 
return value from get_cmd_for_pid is NULL. This is 
a problem with this plugin only because it uses a fork
which the shell's SIGCHLD handler will try to handle
and will be unable to find the cmd.
