New Version 0.6.1

I'm releasing 0.6.1 (an update of the 0.6 branch) instead of the planned 0.7 (based on new architecture) - mainly because 0.7's development takes more time than expected and due the recent events. It contains some bug fixes and improvements you have asked for. 0.6.1 improves the performance on linux-system by about 2% - unfortunately it's not possible to take advantage of this particular improvement on windows-systems. I've slightly changed the terminal-ui so if you're parsing it be aware of it. There is a second incompatibility: the cmd-line parameter '--temp-target' supports now the configuration of individual GPUs, it's syntax has changed because of this.

0.6.1
- fix failover-pool not switching back on ssl errors
- fix failover-pool not switching back on some servers

- sort output by gpu_id on term-ui
- colorize temperature above 70°C on term-ui

- improve performance on linux systems by ~2%
