* libmobiledevice maintenance: waiting for device and error handling

reason: libmobiledevice was failing on every situation then: device is not connected, blocked or pairing not complete. considering build process and deployment might take minutes its sad to fail just due to blocked device.
changes: mitigation for these cases done by allowing 20 seconds for user to act to solve the situation:
- if no device connected -- waiting for device
- if device is locked -- waiting for unlock
- if pairing in progress -- waiting to complete

other changes:
- changed logic for picking dev image -- all version are parsed and picked exact or lower (fix for MobiVM#517)
- idea plugin: install was moved inside Run process. As before it was happening on UI thread and entire Idea was frozen (there was no update or locked device retries message);
- using Java9 language level for RoboVM compiler/plugins.
- amount for TODO added to point for code fragments that to be refactored (like Launchers, junit client depends on old structure)
