[rules-dev] dependencies

I've done a bit of refactor. JCI has no been inlined and all it' use of commons-* removed, including commons-logging. I have added mininimal StringUtils and ArrayUtils because decisiontables and ide uses them. The result is we use a lot less dependencies now, so its getting more manageable again. The next stage is to move templates to MVEL, then we can remove antlr-2.7.7 and StringTemplate-3.0.jar. Further to that I have updated Janino and Eclipse to the latest versions, both of which allow you to have static imports while targetting jdk1.4 src, so after M1 I'll update functions to use those, rather than the current hacked function resolvers. The ide plugin is now 7.3MB, much smaller than the plugin size we use th have on first launch. Removing antlr-2.7.7 and StringTemplate will take off a further 600kb. Do we need to package janino with the ide? If we remove janino we take of a further 400kb, taking the plugin size down to 6.3MB. Antlr 3.0 is currently 664kb, if we can strip that down to purely runtime deps only, we might be able to get the plugin dow nto 6MB exactly. Mark
