fix: figure standing on water in the last column not suffering damage
removed static from ms per turn setting
With static, the var is never updated after changing the setting (reported by tibor)
Launch.sh: messages on start, Java <8, and early crash
better spawning of bananabomb shards
It was easily possible to kill a figure by placing a bananabomb right within it. Now shards appear with a NORMED_OBJECT_SIZE distance.
MapWindow: fromJson(), remember gameSettings
* fromJson() to reduce code duplication
* toJson() saved gameSettings (needed for revenge after loading saved game and for ai)
* removed map variable, as it is port of the json
** TODO merge the 1st and 3rd constructor (means making the 2 json formats more similar)
Merge branch 'master' into ai (maintain gameSettings)

Conflicts:

make loading saved game with ai work
