Gigalomania 0.28

FIXED Game hanged on some Android devices when screen was locked and
        unlocked.
FIXED AI no longer sends soldiers to build a tower in a sector occupied by an
        ally (which would result in a loop of continually recalling and sending
        out the army).
FIXED AI no longer keeps mining an element when nothing new could be designed
        anyway (the sector is deemed "used up").
FIXED Soldier walking speed not in sync with animation.
FIXED Improved click/touch locations of building turrets for defenders.
FIXED Factory smoke no longer too heavy when factory first built.
FIXED Smoke effects now change speed with the game time rate.
FIXED Gigalomania window was tiny in Windows 10's task view.
ADDED New tutorial mode.
ADDED New graphics for player avatars (thanks to Macrofeet).
ADDED Animation for nuclear defence firing.
ADDED Exhaust effect for jets.
ADDED Explosions when laser destroys a nuke.
ADDED More music (thanks to Sindre Froyn).
ADDED Support for compiling with Qt Creator.
ADDED Option to quit to desktop during a battle, automatically saving the
        state. The game will automatically resume.
ADDED New "Select all" option for deploying armies.
UPDATED Improved combat logic - was giving too much weight to army size, so
        lots of unarmed men would have an undue advantage.
UPDATED Slowed growth rate (so simply waiting until your population grows is
        now a less useful strategy).
UPDATED Population growth rate now slows from 250-500, rather than stopping
        abruptly.
UPDATED Nuclear weapons now cost 7.5 elements instead of 5.5.
UPDATED Spaceships now require 8 soldiers rather than 10.
UPDATED Improved AI logic when looking for sectors to build new towers: pick
        more randomly, but prefer sectors that already have the AI's soldiers.
UPDATED AI now prefers waiting for population to grow a bit more when
        abandoning a "used up" sector, to avoid leaving weapons behind.
UPDATED Lowered the minimum required attack strength needed by the AI for later
        ages.
UPDATED There are now four difficulty levels.
UPDATED Tweaked some of the elements in islands for better play.
UPDATED Current game state now saved on Android (when app is shutdown by
        Android, or device restarts).
UPDATED Pressing escape or return now closes or accept the confirmations (e.g.,
        for quitting).
UPDATED New game option now goes back to initial screen; new game option also
        available for "Single Island" game type.
