Add ability to specify scratch directory in INI file

[ompiteam]

It would be convenient, especially for #9, to be able to specify the scratch directory in the ini file. It's then one less thing you have to specify on the command line.

(In [665]) Added a scratch parameter to MTT section of INI file.
(Mostly required just moving code around.)

• Moved -f|--file and --scratch parameter processing
• Moved MTT library modules search into BEGIN
• Renamed some vars for clarity in _process_ini_param

Fixes #208

(In [666]) In r665, I forgot to add sample usage of scratch in
[source:/trunk/samples/ompi-core-template.ini](Refs #208).
