KT-3725 Maven pom files, in kotlin libraries, don't have The Central Repository requirements.

I've updated all pom files with all required tags. 

Some default values assinged to tags (for example: developers, name or description), Please feel free to update this values with more suitable one. 

A test release (0.0.1-test-deploy) has been deployed to maven central repository, to verify the potential issues. you can find this release [here in maven central repository](http://search.maven.org/#search%7Cga%7C1%7Corg.jetbrains.kotlin). Please note that this release is based on current snapshots and is only for testing purpose.
