Version 1.02 released

A boring update containing mostly fixes :) There is also an autosave feature which somehow I overlooked in previous versions :)

- [fix] The Hive negative ships.
- [fix] Fighter technology not working.
- [fix] Ships in battle displayed improperly when many ship types.
- [fix] Typos, etc.

- [feature] Autosave (every 5 turns, chan be changed via options).

- [interface] Experimental feature (need to be enabled via options) on research screen which shows some techs stats (very crude, not recommended, later there will be some polished version of it available by default).
- [interface] Battle buttons darked when inactive and improved units display.
