Subject: [PATCH] DATAREDIS-302 - Undo breaking change in
 DecoratingStringHashMapper.

The introduced generic types prevent the DecoratingStringHashMapper from being useful as it can now only be created for mappers of the generic type which was not the original intention.

This breaks the retwis-j sample as well as it seems other implementations see: b0c0d23.

Original pull request: #73.
