Implement packaging of the tool with IDEA artifacts

There were configuration duplication in current setup. It looks like kara.bat and kara.sh scripts ware designed to work only for local environment, so in the packaged Kara nothing worked

I removed older artifacts (that were duplicated in build.xml) and created a set of new ones: kara-core, kara-exec, kara-dist and kara-dist-zip. 

It would be easy to generate `kara-{version}.zip` with help of TeamCity by setting artifact publishing rule `out/artifacts/kara_dist => kara-%build.number%.zip`

I moved all .jar files into lib folder 

It's easy to assume that full kara package is deployed to `out\artifacts\kara_dist` folder
