0.50: no inventory key assigned, keysettings does not save/.

[franko]

Hi,
i noticed that after updating to the new version (0.50 audio update) that no inventory key was assigned (normaly it is "i" but this time the setting filed is just empty). I can assign one in the options and it works but after a restart of the game (even when it not crashed before) the key setting is deleted.
Either the whole keysettings did not get saved after changing or did not get loadad after starting.
