Rewrite startup scripts

[vinjana]

The roddy.sh are a complete mess, without any structure, while at the same time they are also doing a lot of complicated stuff. Simplify.

• Consider implementing with Python or even Groovy. Bash sucks.
• Prepare that startup modes and Roddy options (--optionName) should be all case-insensitive and have the use prefixes discarded. Thus the old annoying --usexy parameters can continue to be used, but in general all documentation and everything ought to use brief camel-case values.
• Remove compilation code from startup scripts. We have Gradle now. And Gradle should be used for everything (compile, test, release, version bumps; maybe even plugin building, testing, releasing).
