ieTanks-engine pom fixing after rebase.
Unfortunately very big commit.

Had to change in very primitive way all of the bot/tank ids from int/Integer to String - bot service has ids in String format and they can contain alphanumeric characters. It can be fixed later.

Finished simple integration with GamePlay. GamePlay class now returns UUID as a result of starting new game. Each game has UUID assigned to it during creation so it is accessible right away.

Introduced BotId class to gameplay module for some typesafety.

BotAlgorithm is (or should be) proper value class - it is no longer an interface.

All tests except one in gameplay module should pass.
Formatting in sandbox module
Added todos for future work
Introduce BotIdJson class to sandbox module that has Jackson annotations for JSON mapping.
