Addded option to raise exception

It used to be a hard-coded class attribute if a robot would
raise exceptions, or error-report them.

This now is changed so that the default is not to raise them,
but you can pass a commandline-argument to make the robot
raise them.
Uppded version because of the new raise exception behavior
Added convenience script to publish new release to internal package server
No dist no more
Asserted that configobj is used as advertised and delivers converted params
Implemented raise_exceptions for writing robot tests, passig config as string
Introduced versioneer
Added explicit manifest to include versioneer.py

Add exception raising option
I added a long-needed command-line option to robots that removes the static RAISE_EXCEPTION declaration into a dynamic option.

Thus you can run robots by hand & get a stacktrace, but when run through e.g. cron, they will use the error-reporting.

Also, I added versioneer.py to produce better package names based on tags and intermediate commits. Thus in the future, the versions of a package depend on a tag in git instead of some hard-coded value.

Last but not least the abl.robot.test now is a bit more featureful, mainly it accepts configurations now as single string, thus allowing more complex ones based on configobj to be tested.
