Protractor Continued - v2.5.1 for KSP 1.0.2

• Fixed bug due to change in API behaviour. Was involving all engines in the burn time calculations. Will now only consider active and operational engines, so burn times should work as before, again.
• The KSP-AVC .version file now has a maximum supported KSP version set to 1.0.*, as I expect it will not break with that version line, and it will be less annoying this way.
