0.2.9.1.1 released

This is just a small update that works around a crash bug in some recent Linux distributions. Confirmed affected were Manjaro users. Very likely, Arch and current Debian users were affected as well. Also very likely affected were users of all distributions who did not have the library SDL1.2 installed on their system, or who opted in to the "Steam Linux Runtime".

A fix to the library bug is underway, but may take a while to arrive for everyone, so a quick fix here was in order.
