ViennaCL 1.1.0 delayed to mid December

The upcoming ViennaCL 1.1.0 is going to be a huge step forward. We are currently fine-tuning the interfaces for the new features (which also include support for multiple GPUs), hunt bugs and extend our automated testing environment. This has turned out to be rather time-consuming, therefore we decided to postpone the release to mid December. Please be patient, we are not going to disappoint you!
