Merge pull request #43 from elzaggo/develop

Added missing files.
Submit now uses old style hadoop param names.

Switched back to old style parameter names for format classes -- e.g.,
mapred.input.format.class. It appears that using the new parameter names
would trigger the use of the mrv2 mapreduce interface, which is not what
pydoop script is expecting.

Some general cleaning, and factoring out argparse types to a new file.
Added debug statement.
Made example mr version agnostic.
Defaulting on old style parameter names.
Refactored script code.

Now it is basically a specialized front end to submit.
