Simplify tech level logic according to TheAiBot's suggestion.
Fix crash when technologiy level stored on the master is greater than the max_level for the technology in Factorio. This can happen with mods that for example reduce the max_level from inifity to a finite level.
Add space between the technology name and the level in the notification for researched technologies.
Rewriwe the researchSync plugin into plugins/research_sync.
