Implement idle command interface as suggested by GvR [idle-dev] 16 July

****************
PyShell: Added functionality:

usage: idle.py [-c command] [-d] [-i] [-r script] [-s] [-t title] [arg] ...

idle file(s)    (without options) edit the file(s)

-c cmd     run the command in a shell
-d         enable the debugger
-i         open an interactive shell
-i file(s) open a shell and also an editor window for each file
-r script  run a file as a script in a shell
-s         run $IDLESTARTUP or $PYTHONSTARTUP before anything else
-t title   set title of shell window

Remaining arguments are applied to the command (-c) or script (-r).

******************
idles: Removed the idles script, not needed

******************
idle:  Removed the IdleConf references, not required anymore
