Resolved terasology server crash issue with log file.

[Christopher Jose]

This is the log for all devs to download, this relates to a headless server.

The crash appears to be caused with cutting trees.

The steps i took leading to the crash as follows

1: Follow the steps used to get resources in the journal to make an axe.
2: craft an axe following the journal crafting guide on the first day of spring.
3: Try and cut a tree down.

This should cause a crash.

For those wondering this is the headless server we've been testing on IRC the last couple days

The very end of the log has 4 access violations, after which the server stops - no more logging

There are a fair amount of modules enabled on the server, including TTA. Lots of unavailable chunk warnings in the full log.

I created the following pull requests to address the permission issues:

• https://github.com/MovingBlocks/Terasology/pull/1438
  
• https://github.com/Terasology/WoodAndStone/pull/29

Thanks for the fixes @Florian

Both are merged now and I've tested around some with a headless server running TtA. With both fixes in place I didn't crash with the steps above, and didn't notice the errors (wasn't really looking though). Although I couldn't actually test it fully the first time due to the update I posted here - the quantum botany made me able to destroy bottom-trunk saplings rather than chop down trees. But after restarting the server (my player identity and op power stayed intact, yay!) I got trunks instead and was able to chop down trees left and right happily.

@Christopher Jose - feel free to retest! Engine source + updated WoodAndStone jar
