RunInXTerm: a simple module to run commands in an X terminal

This is just a wrapper around spawn to launch commands in an X
terminal: runInXTerm will check the for the XTERMCMD environmental
variable, and use it to run the command. If the variable is not set
the command will be executed with xterm.
