Complete Update to riot.js v2.0.15

[codeliner]

Check all components for issues due to the new riot.js version:

• this reference no longer works correctly in listeners, use self or bind listener to this!
• riot-if now removes dom elements instead of hiding them, so callbacks attached with jQuery need to be reattached or even better: use child components and riot moun/unmount functionality
• [x] Check pocess-manager
• [x] Check file-connector
• [x] Check sql-connector
• [x] Check system config
